PowerBoard: common questions

What microcontroller does the PowerBoard use?

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

How big is the PowerBoard PCB?

The PowerBoard measures 77.5 × 108 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the PowerBoard?

60 components, from 36 distinct parts. The full bill of materials is listed on this page.

Where can I download the PowerBoard design files?

From the AUV-IITK/electrical-systems repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the PowerBoard design in my own project?

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

Can I test firmware for the PowerBoard 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.
