What is it?

This is the PCB for the BlueMicro840 with components on 1 side already assembled and soldered on.

What is it for?

The BlueMicro840 is a nRF52840 controller inspired on the Adafruit nRF52840 feather but with the footprint of an Arduino Pro Micro. It can be programmed using standard Arduino tooling and supports the Adafruit nRF52 libraries. It can also be programmed using CircuitPython.

Why did you make it?

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.

What makes it special?

The BlueMicro840 PCB has the same footprint as the Arduino Pro Micro. As such, it makes available 18 GPIOs for your own use. This board is great for upgrading pro micro based keyboards.

The BlueMicro840 PCB has the following features:

LiPo battery charger on board.
USB-C Connector (included but not soldered)

BlueMicro Shipping Policy:

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.
