Powersupply: common questions

What microcontroller does the Powersupply use?

The Powersupply is built around the ESP32-S3-MINI-1U, from the ESP32 family.

How big is the Powersupply PCB?

The Powersupply measures 100 × 100 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Powersupply?

61 components, from 36 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 Powersupply design files?

From the akseliahonpera/embedded_systems_course_26 repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Powersupply design in my own project?

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

Can I test firmware for the Powersupply 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.
