If you can't find a Raspberry Pi, why not make your own? The StackyPi, an RP2040-based board with a Raspberry Pi Zero tiny size, will be delivered by SB Components, the firm behind this Kickstarter. This isn't the first time we've seen anything like this; we recently covered the Red Robotics Pico 2 Pi, which adds GPIO capability to the RP2040-powered Raspberry Pi Pico module. That board, on the other hand, was more of an adapter, whereas this one is a fully functional unit. The StackyPi has two rows of 20 male header PINs ripped out for total GPIO access. The StackyPi is compatible with a broad selection of Raspberry Pi HATs thanks to its GPIO support. The only requirement is that the assistance be designed by the end-user. In addition to the GPIO, SB Components has included a micro SD card connector, 64MB of onboard flash, and a few surface-mounted buttons. A micro-USB port is used to power the StackyPi. StackyPi specifications: MCU – Raspberry Pi RP2040 dual-core Cortex-M0+ microcontroller @ up to 133 MHz with 264KB SRAM Storage – 8MB (64Mbit) SPI flash, MicroSD card socket USB – 1x Micro USB port Expansion – 40-pin GPIO header with GPIO, I2C, UART, SPI, etc… mostly compatible with Raspberry Pi header (3.3V I/Os) Misc. – Reset and Boot buttons Power Supply- 5V via Micro USB port Dimensions – 65 x 30 mm (Raspberry Pi Zero form factor) The StackyPi has two rows of 20 male header PINs ripped out for total GPIO access.

The official Kickstarter website lists a launch price of $18.98 (£14), however it may be available for $9.49 (£7) to early backers.
