Pimoroni Tiny 2350 RP2350 Mini Development Board with 4MB Flash

The Pimoroni Tiny 2350 - 4MB is a postage stamp-sized RP2350 development board featuring a USB-C connection, ideal for portable projects, wearables, and embedded electronics.

Designed by Pimoroni as a smaller, more flash-equipped alternative to the Raspberry Pi Pico, this compact board packs a dual-core Cortex M33 processor running at up to 150MHz, with 512KB of SRAM and 4MB of flash memory all on a tiny PCB roughly the size of a thumb.

Key features include a USB-C port for power, programming and data, a programmable RGB LED, reset and boot (user) buttons, and a Qw/ST (Qwiic/Stemma QT) connector for attaching I2C devices. It has twelve IO pins, including four 12-bit ADC channels. The board’s castellated pads allow direct soldering onto PCBs or use with headers for breadboard compatibility.

The Pimoroni Tiny 2350 is compatible with firmware written for Raspberry Pi Pico 2 and supports programming languages including CircuitPython, Arduino IDE, and MicroPython.

• Powered by RP2350A dual ARM Cortex M33 cores at up to 150MHz with 520KB SRAM
• 4MB QSPI flash memory supporting execute in place (XiP)
• USB-C connector for power, programming, and data transfer
• Programmable RGB LED and user-configurable boot button
• Qw/ST (Qwiic/STEMMA QT) connector for expansion
• Twelve IO pins with four 12-bit ADC channels
• Reset and BOOT buttons (BOOT doubles as user button)
• On-board 3.3V regulator with max 300mA output
• Operating input voltage: 3V - 5.5V
• Dimensions: approximately 22.9 x 18 x 5.8mm (including USB-C port)

Ideal for developers seeking a tiny but capable RP2350 development platform with ample flash and versatile connectivity.
