RK3188-SOM-EVB 개요
A System-on-Module (SOM) is a compact, ready-to-integrate computing block that places the CPU, RAM, PMIC, and boot storage on a single PCB, allowing product engineers to focus their own PCB design on application-specific I/O rather than high-speed memory and power-rail layout. The RK3188-SOM-EVB completes the evaluation toolchain by adapting the SOM's 0.05-inch high-density headers to 0.1-inch standard-pitch headers, so shields, LCDs, and UEXT peripherals can be attached without adapter cables.
Key features include HDMI output, 10/100 Mb Ethernet, four USB 2.0 host ports, one USB OTG port, microSD boot, an LCD connector with resistive touch support, an RTC with coin-cell backup, and a UEXT peripheral socket. The board accepts +6V to +16V DC on a barrel jack and consumes 0.10-0.15 A at 10 V input when combined with the RK3188-SOM-4GB module. Hardware design files are released as Eagle CAD sources and KiCAD templates for the SOM socket are provided.
The architecture follows a modular SOM-plus-baseboard pattern: the RK3188 SoC handles Cortex-A9 cores with NEON and a Mali-400 MP4 GPU, while the AC8846 PMIC manages voltage rails and power sequencing. Compared with discrete layouts, this design eliminates the need to route DDR3 on the carrier board and lets engineers focus on application logic.
Typical applications include Android set-top boxes, HDMI media players, IoT gateways, digital signage, retro handheld gaming, industrial HMIs, and learning platforms for the Rockchip ecosystem. For stable operation, ensure the input supply stays within +6V to +16V DC and that the SOM is firmly seated in its five 40-pin 0.05-inch headers.

일반적인 애플리케이션
RK3188-SOM-EVB 적합 용도: 6 애플리케이션s: Android Set-Top Box Prototyping, Industrial HMI / Digital Signage, IoT Gateway with Ethernet, Retro Handheld / Emulation Platform, Educational Rockchip Development Platform, Custom Industrial Linux Appliance.
Android Set-Top Box Prototyping
The RK3188-SOM-EVB is well suited to Android TV-box prototyping thanks to its HDMI output and the Mali-400 MP4 GPU integrated in the RK3188 SoC. The quad-core Cortex-A9 at 1.6 GHz sustains 1080p hardware decode for H.264 streams, while the EVB's USB-OTG and 4 host ports accept Wi-Fi dongles, IR receivers, and Bluetooth sticks. Compared with bare-bones RK3188 reference designs, Olimex's board exposes every required connector on 0.1-inch headers, eliminating adapter PCB work and shrinking time-to-prototype to a single weekend.
추천
Industrial HMI / Digital Signage
For industrial HMIs, the RK3188-SOM-EVB combines an LCD connector with resistive touch support, a 10/100 Ethernet port, and RTC with backup battery, giving it the essentials for kiosk signage. The 1 GB DDR3 handles typical signage loops, while the +6V to +16V DC input accepts common industrial 12V or 24V adapters. The Mali-400 MP4 GPU drives LVDS-style LCD panels through the carrier board's GPIO mapping, and Olimex publishes the full Eagle CAD schematic so integrators can copy proven routing directly into their own carrier PCB.
추천
IoT Gateway with Ethernet
The RK3188-SOM-EVB's 10/100 Ethernet port and four USB host ports make it a credible Linux-based IoT gateway for factory or lab deployments. Running mainline Linux or OpenWrt forks on the RK3188 SoC, the board can host MQTT brokers, Node-RED flows, or Docker services for edge aggregation. The UEXT socket accepts RS-485, CAN, or 1-Wire modules, extending the gateway into industrial sensor networks without redesigning the baseboard.
추천
Retro Handheld / Emulation Platform
Hobbyists frequently repurpose the RK3188-SOM-EVB as a retro gaming handheld or tabletop emulator. The quad-core Cortex-A9 at 1.6 GHz comfortably emulates systems up to the PlayStation 1 and Nintendo 64 era, while the Mali-400 MP4 GPU handles LCD display output up to 1080p. Pairing the EVB with a 5-inch LCD and USB game controllers through its host ports yields a self-contained emulation platform. The open Eagle CAD files let modders integrate battery chargers and additional buttons in their own derivative carrier boards.
추천
Educational Rockchip Development Platform
Universities and bootcamps use the RK3188-SOM-EVB to teach ARM SoC architecture and Android porting. The exposed GPIO, UART console, and JTAG-style debug headers give students direct access to every peripheral of the RK3188. Olimex's published schematics in Eagle format allow learners to follow power-rail design and DDR3 routing used in real products, then transfer those skills to commercial Rockchip projects.
추천
Custom Industrial Linux Appliance
Engineers building custom Linux appliances benefit from the RK3188-SOM-EVB's modular SOM-plus-carrier pattern: once firmware is validated on the EVB, the same RK3188-SOM can be transplanted into a smaller, application-specific carrier PCB. The AC8846 PMIC handles all rail sequencing, the 1 GB DDR3 supports container workloads, and the open KiCAD template accelerates form-factor redesign. Industrial deployments in lighting controllers, access gates, and CNC front-ends commonly start from this Olimex reference design.

설계 노트
The RK3188-SOM-EVB accepts +6 V to +16 V DC through the female barrel jack (PWR). When paired with the RK3188-SOM-4GB, the combined board draws 0.10 A to 0.15 A at 10 V input per the Olimex user manual. Use a regulated adapter rated at least 1.5 A continuous to handle inrush during Mali GPU ramp-up. Reverse-polarity or under-voltage conditions will prevent boot without a clear error code - measure VIN before debugging the SoC.
The companion RK3188-SOM plugs into the EVB through five 40-pin 0.05-inch high-density headers. Verify all five connectors are fully seated before powering the board; even one partially-mated connector will cause boot failure. The EVB adapts the SOM's 0.05-inch headers to standard 0.1-inch GPIO, but do not attempt to plug a 0.1-inch cable directly into the SOM itself - the pitch mismatch will damage the high-density connector.
Do not confuse the RK3188-SOM-EVB (the carrier board) with the RK3188-SOM (the SoM itself). Powering the EVB without the SOM seated will not produce any HDMI output and may appear bricked. Also note that the RK3188 SoC supports only Cortex-A9 instruction set; mainline kernel patches exist but require kernel 4.x or newer with Rockchip MAINLINE support enabled. Older Android 4.x images will boot but lack modern security patches.
