Pimoroni PIM721 RP2350 development board

SKU CH-C3KZ-S9Y9K

A postage stamp-sized RP2350 development board with USB-C, twelve IO pins and a Qw/ST connector for portable projects

  • Tiny postage-stamp board fits portable projects
  • Dual Arm Cortex-M33 at 150 MHz delivers fast processing
  • 520 KB SRAM plus 4 MB QSPI flash supports XiP execution
  • USB-C provides power programming and data transfer
  • Twelve IO pins with four 12-bit ADC channels expand connectivity

Ultra-compact RP2350 board

The Pimoroni PIM721 is a postage-stamp sized development board built around the RP2350A microcontroller. It provides a dual Arm Cortex-M33 processor running up to 150 MHz with 520 KB of SRAM and 4 MB of QSPI flash supporting execute-in-place. A USB-C connector supplies power, programming and data, and a Qw/ST port allows quick attachment of compatible breakouts.

Makers needing minimal footprint

This board suits developers building portable or space-constrained projects who want RP2350 performance in a tiny package. The twelve IO pins, four ADC channels and user-programmable RGB LED support sensor-rich designs. Builders requiring onboard wireless connectivity, larger pin counts or higher regulator current for heavy peripherals should look elsewhere.

RP2350A dual-core processor

The RP2350A dual-core Arm Cortex-M33 running at up to 150 MHz is the specification that determines whether this board fits the performance envelope of your application. It delivers 520 KB of SRAM and supports XiP from the 4 MB QSPI flash for fast code execution.

Perguntas sobre este artigo

How fast does the RP2350A run in a real project?

The dual Arm Cortex M33 cores reach 150 MHz, giving plenty of headroom for real-time control and signal processing on a stamp-sized board.

What does the USB-C port actually carry?

The USB-C connector supplies power, handles programming and provides a serial data path — all through one cable.

How much current can the on-board 3V3 regulator supply to my add-ons?

The regulator is rated for 300 mA maximum, so budget your sensors and breakouts accordingly.
