The Pimoroni Tiny 2350 packs the power of the RP2350 into a postage stamp-sized board. With 4MB flash, USB-C connectivity, an RGB LED, and a Qw/ST connector, it's perfect for portable projects, wearables, and embedding into custom creations. Compatible with Raspberry Pi Pico 2 firmware, programmable with C/C++ or MicroPython. Castellated pads allow direct PCB soldering, or add headers for breadboard use. Key Features RP2350A Processor – Dual ARM Cortex-M33 at up to 150MHz with 520KB SRAM 4MB Flash – Generous storage with XiP support USB-C – Power, programming, and data transfer RGB LED – User-programmable (PWM dimmable) Qw/ST Connector – Easy I²C breakout connection (Qwiic/STEMMA QT compatible) 12 GPIO Pins – Including 4× 12-bit ADC channels Reset & Boot Buttons – Boot button doubles as user input (GP23) Castellated Pads – Direct PCB mounting option Specifications Processor – RP2350A (Dual Cortex-M33, 150MHz) RAM – 520KB SRAM Flash – 4MB QSPI GPIO – 12 pins (4× ADC) Input Voltage – 3V to 5.5V Regulator Output – 3.3V, 300mA max Dimensions – 22.9 × 18 × 5.8mm Ideal For Wearables and portable electronics Embedding into custom PCBs Space-constrained projects I²C sensor networks via Qw/ST MicroPython or C/C++ development Tip: The RGB LED is active-low (connected to GP18-GP20). The BOOT button can be used as a user switch on GP23. Resources Pinout Diagram (PDF) RP2350 MicroPython & Examples
