Schematic: common questions

What microcontroller does the Schematic use?

The Schematic is built around the 61302011821, from the RP2040/RP2350 family.

How big is the Schematic PCB?

The Schematic measures 150 × 100 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Schematic?

50 components, from 26 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 Schematic design files?

From the picocomputer/schematic 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 Schematic design in my own project?

The repository has no license, so all rights stay with picocomputer. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Schematic 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.
