Tiny 2350 (4MB Headered)

A postage stamp sized RP2350 development board with a USB-C connection, perfect for portable projects, wearables, and embedding into stuff.

While we love the Raspberry Pi Pico we also wanted something smaller and with a bunch more flash on board. Introducing the Tiny 2350 - a teeny tiny powerhouse with the chops to realise truly ambitious projects.

Programmable via USB-C, Tiny 2350 comes with 4MB of flash storage on board. 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, a Qw/ST connector for connecting up I2C devices 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 2 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 2350s available, with downwards pointing pin headers lovingly pre-soldered by pirates.
