Programmable timer for low voltage LED lights (e.g. christmas LED strings) with a Microchip PIC16

A GPRS/GNSS/BTLE and LiPo/Li-ion charger integrated Pi Pico on credit-card format.

KiCad custom design rules (.kicad_dru) matching JLCPCB and PCBWay manufacturing capabilities

This is a powerful and compact Arduino compatible board.

This is a very compact pitch conversion substrate for ESP32-C3.

全屋双色温灯光控制方案 基于 HA 和 ESPHome

Simple current probe to measure current with an oscilloscope

A carrier board for the LuckFox 3506 designed in KiCAD 10

A custom icy-themed USB 2.0 hub with USB-C and USB-A ports, built around the SL2.1A hub controller and packaged in a custom 3D-printed case.

Mini MCP server that drives a running KiCad 10 PCB editor from Cursor over the official IPC API. LCSC/EasyEDA footprints for JLCPCB.

This is a cheap and small Arduino compatible board.

Portfolio PCB: ESP32-S3 Wi-Fi plant monitor. 4-layer KiCad 10 design, fabricated and assembled at JLCPCB — schematic, reviews and the frozen manufacturing package all readable in-browser.

Rotary Encoder with hardware Debouncer

RaspberryPi Zero 2 W addon serving as a handheld photo camera setup

80% Hotswappable split keyboard powered by the Pi Pico, containing OLED screens, rotary encoders, macro keys, and a layout that can snap together to form a full 80% keyboard.

Without using a USB-C PD controller chip, handling communication over the USB cable, USB-C standard allows to get 5V up to 3A through a hardware availability detection. Here I show a design developed on KiCad and made through JLCPCB, powering from a USB-PD source and providing 5V and 3.3 (through a step-down converter) up to 3A.

KiCAD project of PCB that reads data from the Aidon electricity meter's HAN port and converts it to an RS485 bus, enabling integration with home automation systems, data loggers, and industrial equipment.

Kicad project of an STM32-based board climate controller utilizing an RTC module for time-scheduled environmental reading of temperature/humidity with SHT30 sensor and optional small relay for control.

This is a small module that handles the USB PD negotiation and simply outputs a specific DC voltage.
