    The nice!nano is a wireless, BLE enabled replacement for the Pro Micro powered by the nRF52840 SoC.

    DISCLAIMER:

    While the hardware for this product is finished, the firmware and documentation are still being worked on. This means that it'll take more work to set up compared to a non-wireless solution like the Pro Micro or Elite C. You'll also want to source a power source yourself, such as a rechargeable 3.7V lithium battery, though it works on USB power as well. If you are looking to build your first keyboard and are new to electronics, I recommend to go with a wired solution first.

    When using this controller with a keyboard, it is recommended to not install RGB LEDs or OLED displays, as these features generally use 5v, while the nice!nano operates on 3.3v. The features are also power hungry, significantly reducing the usable time of an external battery.

    When using this controller for a split keyboard, you'll need both sides to use a nice!nano, so you'll want to get two nice!nano controllers. This is due to current firmware support and the voltage difference between different controllers.

    Includes square post headers for assembly. It is recommended to socket using Mill Max Low Profile Sockets.

    Using this microcontroller requires an external power source, such as a 3.7v lithium rechargeable battery. One example of a compatible battery is the 301230 lithium battery. Do note that when you intend to use these batteries underneath the controller while socketing the controller, you should use diode legs instead of the Mill Max pins as the pins will be too short. Due to export and shipping restrictions, batteries are not available at splitkb.com.

    For more information including build tips, firmware, and more, read the documentation.

    Features:

    • The mid mount USB-C port makes this microcontroller board 3.2mm thin, saving space when compared to the Pro Micro;
    • nRF52840 chip on board with 1MB of Flash and 256KB of RAM;
    • Comes preloaded with the Adafruit Bootloader, offering DFU flashing as well as flashing via UF2 storage (similar to dragging a file to a flash drive);
    • Programmable blue indicator LED as well as an orange charging indicator LED;
    • Battery voltage reader to report battery percentage to main device;
    • Save power by cutting off external power using an on board MOSFET, saving power from LEDs (each can draw 1mA when off);
    • 5 extra GPIO pins (3 thru holes and 2 pads on the back) offering a total of 23 GPIO pins;
    • 3.3V out of the VCC pin to power external features;
    • 32.768 kHz oscillator on board for real-time clock capabilities;
    • Clean design with matte black solder mask, immersion gold plating, and Tg 170 FR4 for durability.
