SuperMini NRF52840 is a Nice!Nano Wireless alternative development board made to turn your keyboard wireless using ZMK software.
Flashing nice!nano is as easy as a drag and drop.
⚠️ Recommended Soldering Iron Temperature when soldering is 240 Celsius (464 Fahrenheit).
Controllers are heat sensible and fragile components, please handle with care.
⚠️When soldering avoid using high iron temperatures or irons without temperature control, as you could damage the main nRF52840 chip. A temperature around 270°C-300°C should be hot enough. The higher the temperature, the more likely you are to damage the board.⚠️
