ATSAM4S-XPLD - SAM4S Xplained ARM Cortex-M4 MCU Eval Kit | Microchip
The Microchip Technology ATSAM4S-XPLD is an embedded evaluation board built around the ATSAM4S16C microcontroller, an ARM Cortex-M4 32-bit MCU with DSP instructions and floating-point unit, designed for early evaluation of the Atmel/Microchip SAM4S family. The kit integrates a 12 MHz main crystal and a 32.768 kHz low-frequency crystal, an IS66WV51216DALL 8 Mbit SRAM expansion, four Atmel QTouch capacitive buttons, four user LEDs, a Micro-AB USB device port, a Micro-AB USB debug interface (EDBG-compatible) supporting SEGGER J-Link OB and a Virtual COM Port, and dual Xplained expansion headers for analog and digital I/O access. A reset button and one user pushbutton complete the user interface. The board is a Box-packed development kit, listed as Obsolete by some distributors but still supported through Microchip's documentation portal. What is a microcontroller evaluation kit? An evaluation kit (EVK) is a reference design platform that gives engineers immediate access to a vendor's silicon peripherals, debug interface, and expansion ecosystem without spinning a custom PCB. The ATSAM4S-XPLD belongs to the Xplained family of kits, which standardise on-board debugger silicon, dual-row expansion headers, and Atmel QTouch buttons so code developed on one Xplained board ports quickly to another. In the broader hierarchy it sits at: evaluation board -> development platform -> engineering tool for 32-bit ARM Cortex-M microcontrollers -> Microchip/Atmel SAM family. Key features include the SAM4S16C Cortex-M4 core running up to 120 MHz, 1 Mbyte of embedded Flash, 128 Kbytes of SRAM, USB 2.0 Full-Speed device, up to 47 I/O lines routed to the Xplained headers, and on-board voltage regulators accepting an external supply. Software support is provided through Microchip Studio / Atmel Studio, MPLAB Harmony, and the Zephyr RTOS Board Support Package, all of which recognise the board's hierarchical identifier `atmel,sam4s_xplained` in their device trees. The kit targets typical application scenarios including industrial HMI prototypes, USB device peripherals (CDC/HID/MSC), low-power wireless sensor nodes paired with an external radio board, motor control evaluation with companion Xplained boards, and rapid proof-of-concept work for Cortex-M4 DSP routines. Design consideration: the EDBG USB port enumerates as both a debugger and a COM port simultaneously, so Windows/Linux hosts must install the EDBG driver or use the latest Zephyr/Studio tools for plug-and-play. The kit is functionally comparable to the SAM4L8 Xplained Pro (ATSAM4L8-XPRO) but with a Cortex-M4 instead of Cortex-M3 core. This page synthesizes distributor stock/pricing data, on-board peripheral inventory, and practical bring-up notes so an engineer can decide whether the ATSAM4S-XPLD is the right starting point for a SAM4S-based product.
ATSAM4S-XPRO - SAM4S Xplained Pro ARM Cortex-M4 Eval Kit | Microchip
The Microchip Technology ATSAM4S-XPRO is a SAM4S Xplained Pro evaluation kit built around the ATSAM4SD32C microcontroller, an ARM Cortex-M4 MCU running at up to 120 MHz with 2 MB Flash and up to 160 KB SRAM. The board integrates an onboard embedded debugger (EDBG) for drag-and-drop programming and virtual COM port, plus three Xplained Pro extension headers for plug-in modules such as OLED1, I/O1, and PROTO1. An Xplained Pro board is a Microchip/Atmel evaluation platform that combines a target microcontroller with a unified extension header ecosystem, allowing engineers to mix and match peripheral add-on boards without rewriting BSP code. Within the broader taxonomy, this kit sits under evaluation boards -> development boards -> microcontroller starter kits -> ARM Cortex-M4 prototyping platforms. It is designed to shorten the bring-up cycle for SAM4S-based industrial, consumer, and IoT designs. Key features of the ATSAM4S-XPRO include the ATSAM4SD32C Cortex-M4 core with single-precision FPU, 2 MB embedded Flash, 160 KB SRAM, and an external 2 GB NAND Flash interface exposed on the board. The kit is USB-powered through a Micro-B connector and exposes the full SAM4S peripheral set including USB 2.0 Full-Speed, EMAC, HS MCI, multiple USARTs, SPIs, TWIs, and a 12-bit ADC. The package here is the PCB itself; the MCU on board is the ATSAM4SD32C in a 100-pin LQFP. Typical applications include rapid evaluation of the SAM4S microcontroller family, prototype development for smart-energy metering, industrial HMI, USB peripherals, secure connected nodes using SAM4S crypto peripherals, and low-power battery-backed IoT gateways. Designers can immediately evaluate FreeRTOS, ASF (Atmel Software Framework) libraries, and Atmel Studio 7 / Microchip Studio workflows out of the box. When selecting this kit, ensure your host PC has a USB 2.0 port for power and debug. The EDBG debugger enumerates as a composite HID/MSD/VCP device, so first-time use may require drivers from Microchip. Because the kit does not ship with extension boards, plan to order I/O1, OLED1, or PROTO1 Xplained Pro modules if a richer peripheral demonstration is required.
ATSAM4S-XSTK - SAM4S Xplained Pro ARM Cortex-M4 Starter Kit | Microchip
The Microchip ATSAM4S-XSTK is a SAM4S Xplained Pro Starter Kit built around the ATSAM4SD32C ARM Cortex-M4 microcontroller, providing engineers a complete out-of-the-box evaluation platform. The kit ships with the ATSAM4S-XPRO evaluation board plus three extension boards (I/O1 Xplained Pro, OLED1 Xplained Pro, and PROTO1 Xplained Pro), two USB cables, and full Atmel Studio integration. The on-board SAM4SD32C MCU runs at up to 120 MHz with 2 MB of Flash and 160 KB of SRAM, with a multi-layer bus matrix, multi-channel DMA, and Flash read accelerator for high data-rate communication. A development kit (or evaluation board / starter kit) is a populated PCB that exposes every peripheral of a target MCU so firmware engineers can validate software, benchmark peripherals, and prototype end products without spinning a custom board. Within Microchip's portfolio, evaluation kits sit beneath complete development kits: the bare ATSAM4S-XPRO contains only the main board, while the ATSAM4S-XSTK bundles extension boards into a ready-to-run package. This hierarchy (evaluation board -> starter kit -> reference design -> production PCB) helps engineers select the right starting point for each project phase. Key features of the on-board SAM4SD32C include the Cortex-M4 core with single-precision FPU, DSP extensions, a full-speed USB 2.0 device/host with on-chip PHY, up to 8-channel 12-bit ADC, two I2S interfaces, three USARTs, two UARTs, two TWIs (I2C), two SPIs, an external bus interface, and a 16-bit static memory controller. The device operates from 1.62 V to 3.6 V and includes a 32 kHz crystal (0.032768 MHz) for low-power RTC operation. The board exposes the standard Xplained Pro extension headers and the DEBUG USB / Data Gateway USB ports. The SAM4S architecture uses a multi-layer AHB bus matrix with independent SRAM banks and a peripheral DMA controller, enabling deterministic parallel access between CPU, bus masters, and high-speed peripherals (USB, EMAC). This contrasts with simpler Cortex-M0/M0+ designs that share a single bus, making the SAM4S better suited for applications juggling USB traffic plus motor control or audio streams simultaneously. Typical applications include USB peripherals (HID, CDC, mass storage, audio), industrial motor control (BLDC, stepper), smart energy metering, HVAC control panels, building automation, point-of-sale terminals, and medical low-end instruments. The OLED1 extension board lets users immediately demonstrate graphics while the PROTO1 area provides prototyping space for custom circuitry. Audio codec examples from the Atmel Software Framework demonstrate the I2S peripheral and DMA-driven streaming. When bringing up a SAM4S design, program and debug through the on-board Embedded Debugger (EDBG) over the DEBUG USB port; no external programmer is required. The free Atmel Studio / Microchip Studio IDE, ASF (Atmel Software Framework), and a GCC toolchain all support the kit directly. For production migration, pin-compatible SAM4S family variants (SAM4S16, SAM4S8, SAM4S4) are available in LQFP and QFN packages. This page synthesizes distributor pricing, equivalent development kits, and practical bring-up guidance not consolidated on the manufacturer product page, helping engineers quickly decide whether the ATSAM4S-XSTK is the right starting point for their Cortex-M4 design.

The kit typically includes on-board debug, expansion headers, and example firmware so that firmware engineers can begin code bring-up within minutes rather than spend weeks on base-board design. The SAMA5D2 Xplained Ultra board is the recommended starting point for engineers evaluating the SAMA5D2 family for human-machine interface (HMI), connected-edge, secure-payment, and low-power industrial applications. The board includes a high-speed USB device/host port, a Gigabit Ethernet interface, an LCD connector, audio codec and Class-D amplifier outputs, and mikroBUS / XPRO / Xplained-extension headers for stacking compatible click boards and extension modules. The kit is supported by Microchip's MPLAB Harmony 3 and the mainline Linux distribution distributed through Buildroot and the Microchip linux4sam GitHub. The on-board SAMA5D27 SoC integrates advanced security features such as secure boot, hardware cryptography, and tamper detection, making the board well suited for prototyping secure IoT gateways and edge devices. Typical applications include HMI prototypes with LVDS or RGB LCD displays, secure-connected gateways, building automation controllers, low-power industrial control, and edge-node IoT products. When designing a custom baseboard, engineers reuse the SAMA5D2-XULT schematic as a reference and migrate to a production-grade ATSAMA5D27C-D1G-CU or ATSAMA5D28C-D1G-CU when cost-down is required.
ATSAMA5D27-SOM1-EK1 - SAMA5D27 ARM Cortex-A5 500MHz Eval Kit
The Microchip Technology ATSAMA5D27-SOM1-EK1 is a fast prototyping and evaluation platform built around the ATSAMA5D27-SOM1 System On Module, which embeds the ATSAMA5D27C-D1G-CU System-in-Package integrating a 32-bit ARM Cortex-A5 MPU core and 1-Gbit (128 MB) DDR2 SDRAM in a single BGA package. The kit comprises the baseboard with the ATSAMA5D27-SOM1 module soldered on, exposing the full peripheral set of the SAMA5D2 SiP family, including 1-Gbit DDR2, 64-Mbit NOR Flash, and 1-Kbit EEPROM for fast Linux and RTOS bring-up at a 500 MHz core clock. The ATSAMA5D27-SOM1-EK1 is designed for evaluation of both the SAMA5D2 SIP and the SOM1 form factor, supported by Microchip's mainline Linux distribution, Buildroot, and Yocto BSPs. An evaluation kit (EK) is a printed-circuit-board hardware development platform that integrates the target SoC/SiP with power, memory, debug, and standard I/O headers so engineers can validate firmware and applications before designing a custom carrier. The ATSAMA5D27-SOM1-EK1 sits at the top of the SAMA5D2 evaluation hierarchy above discrete SAMA5D2 Xplained boards, providing the lowest-effort path to running embedded Linux on a Cortex-A5 with hardware-floating-point and rich connectivity. Key features of the baseboard include an on-board debugger, multiple mikroBUS sockets, an LCD/touch connector, USB device and host ports, Ethernet (GMII/RGMII expansion), CAN, two SD card slots, JTAG/SWD, audio codec interface, and expansion headers that map nearly every SAMA5D2 signal to a 0.1-inch header. The integrated Power Management IC and secure-element footprints on the ATSAMA5D27-SOM1 module simplify power-tree design and security key storage for IoT edge nodes. The SAMA5D27 SiP architecture pairs the Cortex-A5 core with a peripheral set including 12-bit ADC, hardware crypto accelerators (AES, SHA, TRNG), and a 24-bit peripheral-touch controller, allowing the same evaluation kit to be reused across HMI, connectivity gateway, and secure-credential prototypes. The DDR2 interface is fully validated at 500 MHz, removing the timing and signal-integrity work normally needed for production designs. Typical applications include industrial HMI panels, smart-home gateways, edge IoT sensors with secure boot, Linux-based point-of-sale terminals, and connected-utility metering. Designers also reuse the kit as a low-volume ODM reference for products based on the ATSAMA5D27 SiP. A single design consideration dominates: when migrating to production, swap the kit's baseboard for a custom carrier that hosts the ATSAMA5D27-SOM1 module directly - the pinout is documented in the SOM1 datasheet. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet.

The board's peripherals mirror many industrial SBC requirements, so it is often used as a software-evaluation platform even when the production hardware is a custom design. When ordering, engineers should verify the variant because the Xplained kit uses the SAMA5D36 die. The board is supplied with a micro-AB to Type-A USB cable for power and debug; users supply their own USB-to-serial or external JTAG probe only if they want to bypass the on-board debugger. This page synthesizes distributor pricing, key pin/feature data from the manufacturer user guide, and practical design considerations not found in the datasheet alone.
ATSAMA5D31-EK - SAMA5D31 ARM Cortex-A5 Evaluation Kit | Microchip
The Microchip Technology ATSAMA5D31-EK is a full-featured evaluation kit (EVK) for the Atmel SAMA5D31 ARM Cortex-A5 embedded microprocessor unit (eMPU), which operates up to 536 MHz with 32 KB each of L1 instruction and data cache, 128 KB of internal SRAM, and an integrated hardware floating-point unit. The kit combines a main baseboard with a detachable SAMA5D3 computer-on-module (COM) and ships with free-of-charge Linux support, providing fast prototyping for industrial, consumer, and human-machine-interface (HMI) designs. The MPU integrates a 24-bit LCD controller, EMAC, USB, CAN, and SD/MMC interfaces on-chip, eliminating the need for external media controllers. An ARM Cortex-A5 based microprocessor unit (MPU) is a high-performance 32-bit application processor that executes a full operating system (typically Linux) with memory management, in contrast to a microcontroller (MCU) which typically runs a bare-metal or RTOS workload. The SAMA5D3 family sits at the top of Microchip's Cortex-A5 portfolio, above Cortex-M4 microcontrollers, offering DMIPS-class performance with sub-mW low-power modes, making it suited for battery-powered graphical terminals as well as line-powered HMI panels. Key features of the target SAMA5D31 silicon (datasheet Doc ID 11224c) include the ARM Cortex-A5 core at 536 MHz, hardware floating-point unit, 32 KB L1 cache per way, 128 KB SRAM, 16-bit DDR2/LPDDR/LPDDR2 controller, 24-bit LCD controller up to 1024x768, 10/100 EMAC with IEEE 1588, two high-speed USB 2.0 hosts plus one USB device, two HSIC ports, two CAN-FD, three SSC/I2S, two SPI, two TWI (I2C), a 12-bit ADC, and a hardware crypto accelerator supporting AES, SHA, and TRNG. The evaluation kit exposes all these through headers, the on-module DDR2 memory, NAND/eMMC footprint, audio codec, Ethernet PHY, and capacitive-touch daughter-board connectors. Typical applications for the ATSAMA5D31-EK include industrial HMI panels, smart-home gateways, point-of-sale terminals, medical patient-monitors, building-automation controllers, low-cost Linux thin clients, and graphical IoT edge nodes. Engineers use the kit to evaluate Linux bring-up, validate LCD + touch + Ethernet throughput, prototype CAN-FD automotive-cluster nodes, and benchmark power modes before committing to a custom PCB design. When using this EVK, ensure the supplied 5 V adapter is used; higher voltage can damage the on-module regulators. For production migration, footprint-compatible SOM carriers such as the ATSAMA5D2-XULT or ATSAMA5D2B-XULT share pin assignments but use a different SoC variant. Pin-compatibility therefore requires SoC-level matching, not just board-mechanical matching.
