The Olimex PICO2-XXL is an RP2350-based development board exposing all 48 GPIO from the Raspberry Pi RP2350B microcontroller!

The board features USB-C for power and programming, RESET and BOOT buttons, upright Qwiic/Stemma QT port, status LED and a pUEXT connector.

This XXL version of the Olimex PICO2 board range comes with some extra features - 16MB external flash (vs the 2MB on the PICO2-XL) and a compact MicroSD slot on the underside of the board.

The board features unpopulated pads for adding your own headers or soldering wires directly.

We also stock the Olimex PICO2-XL, a more affordable variant with 2MB external flash, no PSRAM and no MicroSD slot.
