Pimoroni Tiny 2350 4MB Headered development board

SKU CH-5AC4-03R3B

Postage-stamp RP2350 board with 4 MB flash, USB-C, RGB LED, Qw/ST connector, twelve IO pins and 300 mA 3 V3 regulator

  • Dual Arm Cortex M33 at 150 MHz for fast embedded processing
  • 4 MB QSPI flash with XiP support stores large firmware
  • USB-C provides power, programming and data in one port
  • 12 IO pins with four 12-bit ADC channels for sensors
  • Pre-soldered downwards headers enable instant breadboard use

Tiny 2350 4MB Headered Development Board

The Tiny 2350 is a postage-stamp-sized RP2350 development board aimed at makers who need a compact microcontroller with generous flash. It delivers a dual-core Arm Cortex-M33 running at up to 150MHz, 520KB of SRAM and 4MB of QSPI flash for execute-in-place code storage.

Pre-soldered Headers and Qw/ST Connector

Downward-facing pin headers are factory-fitted, so the board drops straight onto a breadboard or custom PCB without extra soldering. A Qw/ST connector provides plug-and-play I2C expansion for breakouts, while a user-programmable RGB LED and a BOOT button that doubles as a user input give immediate feedback and control.

Power Budget and Pin Count

The on-board 3V3 regulator supplies a maximum of 300mA, so any attached peripherals must stay within that current limit. Only twelve IO pins are exposed, including four 12-bit ADC channels, which is fewer than the full RP2350 pinout; verify that your project can fit within this reduced I/O before ordering.

Questions about this item

How long will the on-board 3V3 regulator rated at 300mA last before it might need replacement?

The 300mA regulator is a surface-mount component soldered to the board and is not designed for user replacement; if it fails the whole board would need to be swapped.

What limit appears first when the dual Arm Cortex M33 cores run continuously at 150MHz?

Sustained 150MHz operation is limited by the 300mA regulator current budget and the resulting heat dissipation in the tiny form factor.

How much noise, heat or extra power draw does the board produce when running all day?

The board has no fan and draws only the current needed by the RP2350A and attached breakouts, so it runs silent with minimal heat under the 300mA regulator limit.
