Bring your Raspberry Pi Pico or Pico-pin-compatible boards into the standard Raspberry Pi (Zero) form factor with this funky adapter board from Pi Hut. This HAT-compatible GPIO mapper is a takes your classic RP2-based Pico style dev boards and shimmies them around into the 2x20 connector featured on the Raspberry Pi computers.

This enables you to plug the hundreds of available bonnets, HATs, pHats, etc. into your favorite microcontroller boards! Develop ever-faster by combining the speed and lightweight nature of the Pico with the ecosystem of Raspberry Pi HATs - use the pinout to see where pins are mapped to.

Please note: Just because there's a mechanical connection does not mean firmware exists to run the code for the HAT/Bonnet! For example, some HATs like our Servo Bonnet will work with an PCA9685 driver. However, other boards like the Voice Bonnet would require someone writing a WM8960 codec driver for CircuitPython/MicroPython/Arduino/Pico SDK which may not exist!

The color-coded 40-pin header also makes developing on your Pico boards easier than ever, whether or not you have HATs to incorporate into your project.

Plus, with 8 GPIOs exposed underneath, along with 5V, 3.3V, and 2x GND pins, you can leverage the full flexibility of the Pico's adaptable pin configurations.

Note: Raspberry Pi Pico not included. There's also no pullups on the SDA/SCL lines so some HATs/Bonnets that expect the 1.8K resistors on a Pi may need external resistors added.
