ESP32 ATX Power Controller
Based on https://www.instructables.com/DIY-1kW-MPPT-Solar-Charge-Controller/ Since I wanted to be able to change the board layout and to test KiCad I decided to give this "conversion" a try.
PCB design (Kicad) to test the DPP architecture used in MPPT designs
KiCad design files for a wattmeter built with a Raspberry Pi Pico and an INA219 power monitor.
Physics Sensor Cube Tux³
A Custom STM32 board that runs on a battery with MCP73831 and is easily programmable with USB thanks to the CP2102 USB-to-UART chip.
Hardware design files for Cubesat PCBs
KICAD project of V2 version of MPPT controller
WASAロケットプロジェクト 共通電装基盤
Solar panel boards for the PyCubed-Mini PocketQube platform
This repo contains open source PCB designs used in conjunction with Ubo Pod other open source system components.
Project contains BMS for lead-acid batteries and ESP-based board used to pull information from EASUN offgrid inverter, energy meters and sensors. It show informations od displays and use ESPhome to send it to Home Assistant..
OreSat solar array designs and CAD
☀️ KiCad-based LT3652 solar battery charge controller PCB with solar input, battery charging terminals, charge/fault status header, adjustable control, schematic, PCB layout, and 3D renders.
Solar powered noise measuring business card
This project is a custom ESP32-S3 development board designed using KiCad. It integrates native USB-C programming, efficient power regulation, and GPIO breakout, eliminating the need for an external USB-to-UART converter. The design follows Espressif reference guidelines and is suitable for IoT and embedded applications.
