Panel: common questions

What microcontroller does the Panel use?

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

How big is the Panel PCB?

The Panel measures 70 × 70 mm, has 4 copper layers and is 1.6062 mm thick.

How many components are on the Panel?

51 components, from 35 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 Panel design files?

From the mikesmitty/electronics-projects repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Panel design in my own project?

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

Can I test firmware for the Panel 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.
