README
README.mdPower Electronics PCBs
Power electronics boards from coursework — physical PCB designs, not just simulation. Each folder is a separate board with its own schematic/layout, a 3D render, and (coming soon) real photos of the built board.
| Project | What it is | |
|---|---|---|
 | scr-controller/ | SCR/thyristor phase-control firing board |
 | buck-converter-24-120v/ | Buck converter, 24 V input target |
 | classd-amplifier-stm32/ | Class D amplifier, STM32-controlled switching |
 | power-supply-protected/ | Voltage supply with short-circuit protection (power + control boards) |
 | ac-dc-inverter/ | AC-DC inverter |
All of these were built as coursework together with Iker Garcia DasReyxr and Kevin Lara — the original combined project history lives in DasReyxr/HW-Projects. This repo pulls out just the PCB projects, one per folder, with proper writeups and renders instead of a mixed dump of exam/simulation files.

Questions
How big is the SCH PowerSupply PCB?
It measures 94.1 × 121.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the SCH PowerSupply use?
47 parts, built around the LM358P, LM317T, 74LS00SC and CD4043BE. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the SCH PowerSupply KiCad files?
From the UAA-F14/PCBs-Design repository on GitHub, at the commit this page was made from: the board is power-supply-protected/design/SCH_PowerSupply/SCH_PowerSupply.kicad_pcb and its schematic ac-dc-inverter/design/Inversor/Inversor.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the SCH PowerSupply design in my own project?
Its repository states no licence, so its author keeps all rights: ask UAA-F14 before reusing the design.
