Basic controller: common questions

What microcontroller does the Basic controller use?

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

How big is the Basic controller PCB?

The Basic controller measures 68 × 88 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Basic controller?

46 components, from 21 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 Basic controller design files?

From the mekatrol/electronics 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 Basic controller design in my own project?

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

Can I test firmware for the Basic controller 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.
