Main components
2README
README.md⚡ USB-C Power Module
A compact, open-source power delivery board that regulates USB-C input into clean, stable voltage rails while supporting Li-ion/LiPo battery charging and status indication. Designed in KiCad and fully DRC-clean, it's built to serve as a reliable power stage for embedded and portable electronics projects.
Key Features
- 🔌 USB-C Power Delivery — Accepts standard USB-C input for power, eliminating the need for legacy micro-USB or barrel-jack connectors.
- 🔋 Battery Charging & Connectivity — Integrated charge management for single-cell Li-ion/LiPo batteries via the TP4056 charger IC, with a dedicated battery connector.
- 📟 Regulated Voltage Rails — Clean, stable 3.3V output using the AP2112K low-dropout (LDO) regulator, suitable for powering microcontrollers and sensitive analog/digital components.
- 💡 Status Indicator LEDs — Visual feedback for charging state (charging / fully charged) and power-good status at a glance.
- 🧰 Filtered, Noise-Resistant Design — Input/output capacitor filtering to smooth voltage ripple and suppress transient noise.
- ✅ DRC-Clean Layout — Passed KiCad's Design Rules Check with 0 errors and 0 warnings.

Questions
How big is the Usb c power module PCB?
It measures 109 × 66.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Usb c power module use?
13 parts, built around the AP2112K-3.3 and TP4056-42-ESOP8. 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 Usb c power module KiCad files?
From the Anuva01/usb-c-power-module repository on GitHub, at the commit this page was made from: the board is USB_C_Power_Module.kicad_pcb and its schematic USB_C_Power_Module.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Usb c power module design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
