PICO2: common questions

What microcontroller does the PICO2 use?

The PICO2 is built around the RP2350B(QFN-80_10.00x10.00x0.90mm_P0.4mm), from the RP2040/RP2350 family.

How big is the PICO2 PCB?

The PICO2 measures 29 × 51 mm, has 4 copper layers and is 1.578 mm thick.

How many components are on the PICO2?

76 components, from 39 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the PICO2 design files?

From the OLIMEX/RP2350-PICO2-XXL repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the PICO2 design in my own project?

Yes, under the terms of its GPL-3.0 license, which OLIMEX chose for the repository.

Can I test firmware for the PICO2 without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
