Sata psu: common questions

What microcontroller does the Sata psu use?

The Sata psu is built around the ESP32-C3_SUPERMINI_TH, from the ESP32 family.

How many components are on the Sata psu?

27 components, from 14 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 Sata psu design files?

From the majabojarska/sata-psu repository on GitHub, which has the schematic and the BOM; the links under Design files point to each one.

Can I use the Sata psu design in my own project?

Yes, under the terms of its MIT license, which majabojarska chose for the repository.

Can I test firmware for the Sata psu without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
