MicrocontrollerInputModule: common questions

What microcontroller does the MicrocontrollerInputModule use?

The MicrocontrollerInputModule is built around the C2040, from the RP2040/RP2350 family.

How big is the MicrocontrollerInputModule PCB?

The MicrocontrollerInputModule measures 31 × 111.4 mm, has 2 copper layers and is 0.955 mm thick.

How many components are on the MicrocontrollerInputModule?

337 components, from 19 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 MicrocontrollerInputModule design files?

From the corndog2000/RGB-LED-Matrix-Input-Module 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 MicrocontrollerInputModule design in my own project?

It is published under CC-BY-NC-4.0, which limits how it may be reused; read the license before building on it.

Can I test firmware for the MicrocontrollerInputModule 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.
