PIMORONI Tiny 2350 RP2350 Microcontroller Board
Compact Pimoroni Tiny 2350 RP2350 microcontroller board with 4MB flash, USB-C, and Qw/ST connector. Ideal for wearables.
The PIMORONI Tiny 2350 is a remarkably compact RP2350 development board, roughly the size of a postage stamp. This diminutive footprint makes it an excellent choice for integrating into portable projects, wearables, and space-constrained embedded designs where size is a critical factor.
Despite its tiny stature, this microcontroller board is packed with features. It is programmable via a USB-C connector and comes equipped with 4MB of QSPI flash storage supporting Execute in Place (XiP). The board is designed with castellated pads, allowing it to be directly soldered onto a PCB for permanent installations.
Hardware highlights include a programmable RGB LED indicator, a reset button, and a Qw/ST (Qwiic/STEMMA QT) connector for easily attaching I2C breakouts. Ingenious circuitry also allows the BOOT button to function as a user-controllable switch.
Powered by the RP2350A chip, it features a Dual Arm Cortex M33 processor running at up to 150MHz alongside 520KB of SRAM. It provides twelve IO pins, including four 12-bit ADC channels. The board is compatible with firmware built for the Raspberry Pi Pico 2 and can be programmed using C/C++ or MicroPython.
