The KiCad project lives in the MUNAKATA-EPC/Artemis_2025 repository on GitHub; these links point at the commit this page was built from.

PSU: common questions

What microcontroller does the PSU use?

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

How big is the PSU PCB?

The PSU measures 38 × 37.2 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the PSU?

46 components, from 26 distinct parts. The full bill of materials is listed on this page.

Where can I download the PSU design files?

From the MUNAKATA-EPC/Artemis_2025 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the PSU design in my own project?

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

Can I test firmware for the PSU 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.
