StackyPi – Raspberry Pi RP2040 based Board in a Pi Zero format

by rp2040guy71

In this article, we look at a board from SBcomponents that combines an RP2040 in a Raspberry Pi Zero format.

The StackyPi is a compact RP2040-based development board with the same physical kind factor and pin layout as the Raspberry Pi Zero, this allows you to connect your existing Raspberry Pi HATs or simply use it as a funky little Pico alternative!

This means that you can fit a HAT created for the Raspberry Pi, but utilize the RP2040 to control it utilizing MicroPython or C/C++ similar to the Raspberry Pi Pico.

So it’s like a Raspberry Pi Pico compressed into Pi Zero pants with some extra little functions on top

The StackyPi consists of a Micro-USB port for power, 64MB flash memory, a BOOT and RESET button for the RP2040, a MicroSD port, status, and power LEDs, and pin breakouts.

The board has a 2×20 40-pin header with the very same dimensions as the header on a Raspberry Pi 4/3/Zero, and the exact same power pins (the IO pins are various of course – this is where your code is available!).
