The NanoBit is an adapter board that allows the Arduino Nano RP2040 Connect to be connected to micro:bit accessories.

The micro:bit has been around for a number of years has a large number of accessories have been produced, many of which I have purchased and made projects with, so I wanted to make those accessories easily connectable to the Pi Pico range of accessories.

Using the NanoBit it is also possible to connect the Arduino to Raspberry Pi HATs via the use of other existing micro:bit adapters.

What's in the box:

NanoBit:

• 1x PicoBit PCB

NanoBit + Headers:

• 1x PicoBit PCB
• 2x 15 Female pin low-profile headers

The Arduino Nano RP2040 Connect is not included but can be ordered elsewhere.

The pin mappings have been carefully chosen to help with existing micro:bit code and accessories.

The NanoBit has been tested with over a dozen micro:bit accessories, and a few Pi Hats.

There is plenty of example source code for using it with Arduino, C & CircuitPython.

The NanoBit has been tested with a Pi Pico and these micro:bit (and Pi) add-ons:

• 4Tronix BitBotXL
• Kitronik GameZip
• Kitronik Piano*
• Mime - MeArm
• Pimoroni EnviroBit
• Pimoroni NoiseBit
• Pimoroni ScrollBit
• Pimoroni TouchBit
• Pimoroni Piano HAT*
• Pimoroni Speaker PHAT*
• ProtoPic MicroPixel Edge
• ProtoPic Simon Says
• WaveShare LCD

*requires 4Tronix Bit:2:Pi

Because the Nano Connect is a Wifi enabled device there are other examples:

• Pimoroni EnviroBit sensor uploads to Adafruit.IO
• Kitronik MiniMove remote control via a web browser.
