Arduino Compatible
Flashed via Arduino IDE without issues using the Adafruit nRF52 board package. Great for prototyping IoT devices.

Great Specs, Tricky Soldering
Works well but the pins are close together. Make sure you have a fine tip soldering iron. Performance is excellent once installed.

Ideal for ZMK Keyboards
Replaced my old ProMicro with this for a wireless mechanical keyboard build. The ZMK firmware flashed easily and the Bluetooth connection is very stable.

Better than Nice!Nano
More accessible pins for my specific case design. Functionality is identical to the nice!nano V2.0 but easier to source.

Stable Bluetooth Connection
Pairing is quick and reliable. I am using this for a custom HID project and haven't experienced any dropouts so far.
Q: Is 5V input safe for the GPIO pins?
A: No, the logic level is 3.3V. Please use level shifters if interfacing with 5V devices to avoid damage.
Q: Can I connect a LiPo battery directly?
A: Yes, there is a JST PH 2.0 connector for LiPo batteries with built-in charging management.
Q: Where is the reset button located?
A: The reset button is located on the backside of the board near the USB connector.
Q: Does this board support QMK firmware?
A: Yes, this board supports QMK via USB connection. For wireless functionality, ZMK firmware is recommended.
Q: Do I need to install specific drivers?
A: It uses a UF2 bootloader, so it appears as a mass storage device. No specific drivers are needed for most OS.
