Excellent for IoT Prototyping
Beyond keyboards, this is a fantastic general-purpose development board. The power efficiency is impressive, and having native USB-C makes debugging much easier compared to older micro-USB boards.

Reliable and Compact
The form factor is incredibly compact yet includes all necessary features including the charge controller. I've used three of these now for different projects, and consistency has been perfect across all units.

Good product, fast shipping
Arrived quickly and was well-packaged. It took me a while to get the drivers set up on Windows, but once that was done, the board worked perfectly. Great entry point for wireless projects.

Great value, minor documentation gaps
The hardware quality is excellent and the nRF52840 chip performs exactly as expected. I deducted one star because the specific pinout diagram for the charging pins could be clearer in the included manual, but online resources filled the gap quickly.

Seamless ZMK Firmware Flashing
Flashed ZMK firmware immediately without any issues. The bootloader is recognized instantly by my computer. The build quality feels solid, and the soldering pads are well-defined for easy modification if needed.

Perfect for Custom Keyboard Builds
This board works flawlessly as a drop-in replacement for the nice!nano. The Bluetooth connection is stable, and the battery charging feature saves so much space on my PCB. Highly recommended for mechanical keyboard hobbyists.
Q: Can I use this board with a 5V logic peripheral?
A: No, the nRF52840 operates at 3.3V logic levels. Connecting it directly to 5V peripherals without a level shifter may damage the microcontroller. Please use appropriate voltage translation circuits for 5V devices.
Q: How do I enter bootloader mode if the automatic trigger fails?
A: If the automatic bootloader entry does not work, you can manually enter bootloader mode by holding the reset button while pressing the boot button (or grounding the specific BOOT pin), then releasing the reset button first.
Q: Does this board support QMK firmware or only ZMK?
A: This board is primarily optimized for ZMK firmware due to its wireless nature and nRF52840 architecture. While QMK is traditionally for wired AVR/ARM chips, community ports for nRF52 exist but may have limited functionality compared to ZMK.
Q: Is the pin header pre-soldered?
A: No, the board ships with an unsoldered pin header set included in the package. This allows you to choose between through-hole mounting or surface mount depending on your specific PCB design requirements.
Q: What is the maximum battery capacity supported by the charging circuit?
A: The integrated charging management supports standard Lithium-Polymer batteries typically ranging from 100mAh to 1000mAh. Please ensure your battery has a standard JST-PH 2.0mm connector compatible with the board.
