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 fewer pins due to its size. You can even run MicroPython on it! Two variants are available - the board only, or with Pre-Soldered Headers Please select an option before adding it to your cart! Features * Powered by RP2350A (Dual Arm Cortex M33 running at up to 150MHz with 520KB of SRAM) * 4MB of QSPI flash supporting XiP * USB-C connector for power, programming, and data transfer * User-controllable RGB LED * Qw/ST (Qwiic/STEMMA QT) connector for attaching breakouts * Twelve IO pins (including four 12-bit ADC channels) * Reset and BOOT buttons (the BOOT button can also be used as a user button) * On-board 3V3 regulator (max regulator current output 300mA) * Input voltage range 3V - 5.5V * Programmable with C/C++ or MicroPython * Dimensions: approx 22.9 x 18 x 5.8mm (L x W x H, including the USB-C port) Resources * RP2350 MicroPython builds and examples * Pinout PDF Version Pinout Notes * It is also useful for putting your Tiny 2350 into bootloader mode, and you can also use the BOOT button as a user switch. It's wired to GP23 and active low. * 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. https://elecena.pl/product/26823161/tiny-2350 2024-08-23 https://elecena.pl/product/26823161/tiny-2350 2024-09-18 https://elecena.pl/product/26823161/tiny-2350 2024-11-29 https://elecena.pl/product/26823161/tiny-2350 2024-11-30 https://elecena.pl/product/26823161/tiny-2350 2025-11-28 https://elecena.pl/product/26823161/tiny-2350 2025-11-29
