Pico Plus 2 RP2350 for embedded developers

The Pimoroni Pico Plus 2 is a microcontroller board built around the RP2350B dual Arm Cortex M33 processor running at up to 150MHz with 520KB of SRAM. It targets makers and engineers who need generous on-board storage and quick peripheral expansion without soldering.

Qw/ST and SP/CE connectors enable solderless

A Qw/ST (Qwiic/STEMMA QT) port allows plug-and-play attachment of I2C sensors and breakouts via cable. An SP/CE connector provides a similar cable-based route for SPI or serial devices. A 3-pin JST-SH debug connector supports SWD debugging, while onboard reset and BOOT buttons add convenient control.

16MB QSPI flash with XiP decides capacity fit

The board provides 16MB of QSPI flash memory supporting execute-in-place operation alongside 8MB of PSRAM. This combination determines whether the available non-volatile storage and volatile workspace meet the firmware footprint and runtime buffer requirements of a given project.

Questions about this item

Will the 16MB flash memory need replacement after repeated programming cycles?

The 16MB QSPI flash supports execute-in-place operation and is rated for typical microcontroller endurance; normal development use will not wear it out.

What limits sustained performance when the dual Cortex-M33 cores run at 150MHz continuously?

The 520KB of on-chip SRAM and thermal envelope of the RP2350B package are the first constraints under heavy continuous load.

How much heat and power does the board draw when powered via USB-C all day?

The RP2350B draws modest current at 150MHz, so the board stays cool and runs from a standard USB-C supply without extra cooling.
