The BlueMacro840 is a nRF52840 controller inspired on the Adafruit nRF52840 feather but with the footprint of an Arduino Micro. It can be programmed using standard Arduino tooling and supports the Adafruit nRF52 libraries.
Many DIY keyboards use the Arduino Pro Micro or the Arduino Micro as their microcontroller. These don't support BLE communications natively. Because the nRF52 chips have a 32-bit ARM Cortex-M4F processor, they have plenty of processing power compared to the traditional AVR chips. The BlueMicro boards were inspired from the Adafruit nrf52 feathers but made to be used directly in DIY keyboards as a replacement for the atmega32u4 based controllers.
The BlueMacro840 has the same footprint as the Arduino Micro. As such, it makes available 23 GPIOs for your own use. This board is great for upgrading pro micro based keyboards.
The BlueMacro840 has the following features:

I collate all orders on Fridays and pack them over the weekend. As such, most shipments will ship on Mondays. However, on holidays and long weekends, shipments may be delayed.
I do ship tracked to Canada and to the USA. International shipping is untracked as it is very expensive to add tracking with CanadaPost.
