The StackyPi from SB Components is a Raspberry Pi RP2040 powered board featuring the Raspberry Pi Zero form factor. This is a really interesting board however it comes in at an price of £14 and doesn't bring much value, as we discuss. It features plenty of user input and expansion in the form of a Raspberry Pi 40 Pin header. It has 8MB of onboard flash storage for your programs and two user buttons and two LEDs and that is about it. The board comes in at 65mm x 30mm x 10mm.

The RP2040 chip supports 4 12-bit ADC channels (4 are user inputs and one measures internal temperature), two UARTs, two SPI and I2C controllers. It also has 8 PIO state machines, USB 1.1 host and device support and 16 PWM channels. Programming any of these Waveshare RP2040 boards is exactly the same as programming the Pico. It can be programmed using the Raspberry Pi RP2040 SDK. Just press the boot select button whilst plugging the USB-C cable in and drag and drop the UF2 file onto the KB2040. It will then reboot and run your program! It can also be programmed in MicroPython and CircuitPython.
