Printed circuit boards designed in KiCad and published on GitHub, each with its parts, layers and size, its README and its files; open any of them in PCBKit.
electgpl/DCDCsyncBuckFSS
This project is the design of a DC-DC buck regulator module based on the AP64501. It is mechanically and electrically compatible with the popular LM2596-based low-cost Chinese modules, using the same form factor, size…
electgpl/ESP32S3_DEV_Minimal_LowPower
This project implements a minimal low-power development board based on the ESP32-S3. The design focuses on reducing component count, board complexity, and idle power consumption, while still exposing the full…
electgpl/MiniUPS12VLead-Acid
This project implements a mini uninterruptible power supply (UPS) designed for 12V Lead-Acid AGM/GEL batteries. It integrates a dedicated CN3767 lead-acid charger, a PMOS + Schottky bypass circuit, a TPS54360 buck…
electgpl/NodeAlarm
This project is a simple motion sensor with subgigahertz FSK interface based on RFM69 and ESP32C3 RISC-V core, all devices are woken from deep sleep by the IRQ of AS312 PIR sensor, this project is open source and…
