RevisedControlBoard: common questions

What microcontroller does the RevisedControlBoard use?

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

How big is the RevisedControlBoard PCB?

The RevisedControlBoard measures 97 × 97.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the RevisedControlBoard?

39 components, from 11 distinct parts. The full bill of materials is listed on this page.

Where can I download the RevisedControlBoard design files?

From the mgamota2/PicoW repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the RevisedControlBoard design in my own project?

The repository has no license, so all rights stay with mgamota2. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the RevisedControlBoard 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.
