From the project
USB Type-C PD Programmable Power Supply
USB-C PD beslemeli, ESP32-C6 tabanlı, TFT ekranlı ve döner enkoderli masaüstü ayarlanabilir güç kaynağı. Şematik ve PCB tasarımı KiCad ile yapılmıştır.
Depo yapısı Open Hardware Template şablonunu izler.
.claude/skills/kicad-schematic/ altında şema üretimi ve temizliği için bir Claude Code skill'i ve iki bağımsız betik bulunur:
render.py şemayı PNG'ye çevirir ve mm cinsinden bir bölgeye yakınlaşır; verify.py ERC çalıştırıp netlist'i bir referansla karşılaştırır. Gereksinimler: kicad-cli, poppler-utils (pdftoppm, pdftotext), Python 3.

Gopo: common questions
What microcontroller does the Gopo use?
The Gopo is built around the ESP32-C6-MINI-1-H4, from the ESP32 family.
How big is the Gopo PCB?
The Gopo measures 99.4 × 61 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Gopo?
125 components, from 70 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 Gopo design files?
From the gokcesena53/usb-pd-power-supply 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 Gopo design in my own project?
Yes, under the terms of its MIT license, which gokcesena53 chose for the repository.
Can I test firmware for the Gopo 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.
