Bulgarian open-hardware specialist Olimex has introduced one other pin-heavy tackle the Raspberry Pi Pico 2, an RP2350B-based improvement board it calls the RP2350-PICO2-BB48 — now bringing out all 48 general-purpose enter/output (GPIO) pins in a breadboard-friendly footprint.
Olimex founder Tsvetan Usunov unveiled his first tackle the Raspberry Pi Pico 2 idea again in November 2024 because the PICO2-XL, a chunky board constructed across the Raspberry Pi RP2350B microcontroller however with doubled header rows to deliver out all 48 general-purpose enter/output (GPIO) pins. This may launch in January this yr because the PICO2-XL and PICO2-XXL, the latter sustaining the footprint however including 8MB of pseudo-static SRAM (PSRAM) whereas bosting the quad-SPI flash storage to 16MB.

Neither design, nevertheless, was breadboard-friendly, regardless of utilizing 0.1″ pin spacing for his or her headers — which is the place the non-XL/XXL RP2350-PICO2-BB48 is available in. Like its predecessors, the board is constructed across the Raspberry Pi RP2350B microcontroller, and like its predecessors it brings out all 48 GPIO pins — however it does so on simply two headers, extending the size of the board quite than its width with the intention to ship breadboard compatibility.
Different options embrace the choice to incorporate the identical beneficiant 8MB of PSRAM and 16MB of flash because the PICO2-XXL, bodily reset and boot buttons, a USB Sort-C connector for information and energy, a 3.3VDC regulator with 2A output, an elective microSD Card slot for added storage, and Qwiic/STEMMA and UEXT connectors for solderless enlargement.
The boards at the moment are obtainable to order on the Olimex retailer, priced at €9.95 for the RP2350-PICO-BB48 with no PSRAM and 16MB of flash and €13.95 for the RP2350-PICO2-BB48R with 8MB of PSRAM, 16MB of flash, and microSD Card slot. As at all times, board designs can be found on GitHub as KiCad mission information underneath the permissive MIT license.
