Olimex PICO2-XL – RP2350 Board with 48 GPIO

The Olimex PICO2-XL 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 more-affordable XL version of the Olimex PICO2 board range comes with 2MB external flash (vs the 16MB on the PICO2-XXL). The board features unpopulated pads for adding your own headers or soldering wires directly.

We also stock the meatier Olimex PICO2-XXL, which has 16MB external flash, 8MB QSPI PSRAM and a MicroSD slot.

Note: The PCB will show as ‘XXL’ as the XXL PCB is used for both variants of this board.
