USB-PD-Power-Supply: common questions

What microcontroller does the USB-PD-Power-Supply use?

The USB-PD-Power-Supply is built around the RP2040, from the RP2040/RP2350 family.

How big is the USB-PD-Power-Supply PCB?

The USB-PD-Power-Supply measures 65 × 50 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the USB-PD-Power-Supply?

65 components, from 31 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 USB-PD-Power-Supply design files?

From the Keyaan-07/USB-PD-Power-Supply 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 USB-PD-Power-Supply design in my own project?

The repository has no license, so all rights stay with Keyaan-07. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the USB-PD-Power-Supply 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.
