Powered and programmable via USB-C, Tiny 2040 comes with 8MB of QSPI (XiP) flash on board (there’s also a budget friendly 2MB version available). The board is designed with castellated pads to allow it to be directly soldered onto a PCB (or you can attach pin headers to hook it up on a breadboard or connect things to it directly with wires). We’ve also managed to fit in a programmable RGB LED, a reset button and some clever circuitry that lets you use the boot button as a user controllable switch.
It’s compatible with firmware built for the Raspberry Pi Pico but offers a reduced number of pins due to its size. You can even run MicroPython on it!
Due to popular demand, we’ve now also got headered Tiny 2040s available, with downwards pointing pin headers lovingly pre-soldered by pirates.

Eagle CAD part
Tiny 2040 is firmware agnostic! You can program it with C/C++ or MicroPython in the same way as you would a Raspberry Pi Pico, though you’ll need to bear in mind that it has a reduced number of pins. You can find (lots) more information on how to do that (as well as download links for the firmware/SDK) on the RP2040 landing page.
You can also use CircuitPython on your Tiny 2040! CircuitPython is an easy to use, well-established ecosystem with lots of example code and drivers for interfacing with different kinds of hardware.
CircuitPython firmware for Tiny 2040: 8MB / 2MB
Getting started guide
The RGB LED is connected to GP18-GP20 and active low (so the on/off state will work in the opposite way to the LED on a Raspberry Pi Pico). You can PWM the pins to dim the LED – check out Tonygo2’s MicroPython example.
