Controller: common questions

What microcontroller does the Controller use?

The Controller is built around the RP2350A, from the RP2040/RP2350 family.

How big is the Controller PCB?

The Controller measures 101.2 × 28 mm, has 4 copper layers and is 1.6062 mm thick.

How many components are on the Controller?

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

Where can I download the Controller design files?

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

Can I use the Controller 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 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.
