Psu: common questions

What microcontroller does the Psu use?

The Psu is built around the KTS1900QGXAA-TA, from the Raspberry Pi family.

How big is the Psu PCB?

The Psu measures 140 × 70 mm, has 6 copper layers and is 1.6 mm thick.

How many components are on the Psu?

243 components, from 62 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 Psu design files?

From the NBence0/JedlikBots 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 Psu design in my own project?

The repository has no license, so all rights stay with NBence0. 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 Raspberry Pi firmware against it before you order a PCB.
