ATR2406-DEV-KIT Overview
An RF transceiver evaluation kit is a complete hardware-and-firmware platform that lets engineers prototype, test, and validate wireless designs before committing to PCB production. In the wireless development hierarchy, a dev kit (board-level platform) sits above the bare IC and below end products, bundling evaluation boards, power supplies, firmware, and design files into a single package.
Key features of the underlying ATR2406 include a fully integrated low-IF receiver, a fully integrated GFSK modulator, an integrated LNA delivering -93 dBm typical sensitivity, multi-channel operation across 95 channels, and a QFN32-packaged single-chip transceiver with image-rejection mixer, low-IF filter, FM demodulator, RSSI, TX preamplifier, power-ramping generator for an external power amplifier, integrated synthesizer, and fully integrated VCO and TX filter.
The kit architecture pairs the ATR2406 transceiver with the ATmega88 flash microcontroller in a reference design documented in Microchip application note doc4624. According to Microchip, the related ATR2406-DEV-KIT2 ships with two ATR2406/ATmega88 boards, two battery packs, AAA batteries, and a CD-ROM containing firmware and manufacturing data including Gerber files, plus adaptive frequency-hopping firmware. The original ATR2406-DEV-KIT evaluation kit also includes a large LCD display and demonstration and testing firmware.
Typical applications include 2.4 GHz ISM-band wireless links, wireless keyboard/mouse and consumer remote control links, industrial telemetry, and low-cost proprietary RF protocol prototyping. The 95-channel capability supports frequency-hopping implementations for coexistence in congested ISM spectrum.
Design consideration: the ATR2406 TX preamplifier includes a power-ramping generator intended to drive an external power amplifier, so plan the output stage matching network and regulatory spurious-emission filtering around your regional 2.4 GHz ISM limit.

Typical Applications
ATR2406-DEV-KIT is suitable for 6 applications: 2.4 GHz ISM Proprietary Wireless Links, Wireless Human Interface Devices, Industrial Telemetry and Sensor Networks, RF Firmware and Protocol Development, Wireless Audio and Streaming Links, Security and Remote Control Systems.
2.4 GHz ISM Proprietary Wireless Links
The ATR2406-DEV-KIT is purpose-built for prototyping proprietary point-to-point and star-network links in the license-free 2.4 GHz ISM band. The ATR2406's GFSK modulation supports data rates up to 1152 kbits/s, its integrated LNA achieves -93 dBm typical sensitivity, and 95-channel operation enables frequency-hopping schemes that dodge interference in congested spectrum. Engineers use the kit's two ATR2406/ATmega88 boards to establish a live RF link on the bench, validate packet error rate at range, and tune the adaptive frequency-hopping firmware before committing to custom PCBs using the supplied Gerber files.
Recommended
Wireless Human Interface Devices
Wireless keyboards, mice, and remote controls are classic ATR2406 use cases: they need modest throughput, low cost, and years of battery life in the 2.4 GHz ISM band. The transceiver's fully integrated signal chain (synthesizer, VCO, TX filter, RSSI) minimizes BOM count, while the -93 dBm typical sensitivity maintains a reliable link across a typical desk-to-PC distance even with small printed antennas. The KIT2's battery-pack operation demonstrates realistic portable power conditions. Firmware on the ATmega88 implements channel hopping and HID-style packet protocols, and the kit's LCD display aids interactive testing of latency and link robustness during development.
Recommended
Industrial Telemetry and Sensor Networks
For factory-floor telemetry, the ATR2406 offers a robust GFSK link with 95 selectable channels and frequency-hopping capability to coexist with Wi-Fi and Bluetooth interference sources common in industrial environments. The kit lets engineers validate link margin through metal racking and machinery by measuring RSSI on the ATR2406's integrated RSSI output, then scaling antenna placement accordingly. With data rates up to 1152 kbits/s, the platform handles periodic sensor bursts comfortably; lower-rate modes recover the full -93 dBm sensitivity for marginal links. The supplied Gerber files allow a fast transition from evaluation to a custom sensor-node PCB matching the mechanical needs of the installation.
Recommended
RF Firmware and Protocol Development
The kit doubles as a firmware development platform for proprietary RF protocols. Microchip's documented reference design (doc4624) pairs the ATR2406 with the ATmega88 flash MCU, and the kit ships with demonstration and testing firmware plus an adaptive frequency-hopping implementation that serves as production-quality starting code. The CD-ROM includes manufacturing data (Gerber files), so engineers can reproduce the layout exactly while iterating on protocol layers. The LCD display on the evaluation board provides immediate visual feedback for testing state machines, hopping sequences, and error handling without attaching external instrumentation to every test session.
Recommended
Wireless Audio and Streaming Links
With GFSK data rates up to 1152 kbits/s, the ATR2406 platform can carry compressed audio streams for low-cost wireless speaker or headphone prototype links. The 95-channel frequency-hopping capability mitigates dropouts in the congested 2.4 GHz band, and the TX power-ramping generator reduces spectral splatter when keying the transmitter, protecting audio quality from transient artifacts. Engineers can benchmark effective throughput on the kit's live RF link before allocating bandwidth to audio codecs, and the -93 dBm typical sensitivity sustains the link across a typical listening room even at furniture-level obstructions and body-blocking conditions.
Recommended
Security and Remote Control Systems
Garage-door openers, alarm peripherals, and access-control remotes benefit from the ATR2406's bidirectional link: unlike one-way 433 MHz remotes, the transceiver enables acknowledgement packets and rolling-code challenge-response over the 2.4 GHz ISM band. The integrated RSSI supports simple presence and link-quality monitoring for tamper detection, and multi-channel hopping frustrates fixed-frequency jamming. The kit's two-board configuration directly emulates a remote-plus-receiver pair for testing pairing procedures, key management, and range limits. Typical +4 dBm output power suits compact antenna designs inside handheld remote enclosures while respecting regional ISM emission limits.

- Multi-device evaluation capability (vs ATR2406-DEV-KIT2)
Design Notes
When cloning the reference design from the kit's Gerber files (provided with the ATR2406-DEV-KIT2 CD-ROM per Microchip), reproduce the PCB stackup and antenna matching network exactly. The ATR2406's -93 dBm typical sensitivity and +4 dBm typical output power were characterized on the manufacturer layout; changing dielectric thickness or trace geometry near the 2.4 GHz antenna feed can detune the match by several dB. Keep the QFN32 transceiver's ground return path solid and place VCO and synthesizer decoupling exactly as in the reference design.
Use the ATR2406 power-ramping generator when driving an external power amplifier. Abrupt TX keying on a +4 dBm (or PA-amplified) carrier creates wideband spectral splatter that violates regional 2.4 GHz ISM spurious-emission limits. Ramp the TX power over the profile supported by the generator, and verify conducted and radiated emissions in a pre-compliance scan before certification testing. In frequency-hopping modes, also confirm per-channel dwell times against your regional regulation (e.g., hopping-system channel requirements).
The ATR2406-DEV-KIT is an Atmel-era product with intermittent distributor stock as of 2026-09-19. Do not design the kit itself into a production test plan; instead, base new hardware on the published ATR2406/ATmega88 reference design (doc4624) and reserve kit units for verification. If your product also uses Microchip's T7024 device, select the ATR2406-DEV-BOARD2, which evaluates both devices together. Confirm ATmega88 firmware compatibility before switching to PB/PA variants of the MCU.
