Clone of OpenBCI Brain Computer Interface Hardware using ESP32 Processor

Simple Number Pad based on RP2040

PT100 + MAX31865 Temperature Data Logger (ESP32-S3, ESP-IDF)

Universal Zigbee Sensor Board (ESP32-H2-Supermini): A KiCad 9.0 project for a versatile, low-power sensor platform using the ESP32-H2-Supermini, designed for easy integration of various sensors in IoT applications.

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..

ASCII Modular hardware and software repo

Open-source KiCAD 7 PCB project for a USB-enabled ATtiny85 Digispark-compatible board. Includes schematic, custom symbols, footprints, PCB layouts, and Gerber's for easy USB microcontroller prototyping and learning modern PCB design workflows.

Extension module for the bGeigieNano kit to add fixed sensor functionality

byrandev, a nRF52840 dev board

Kicad project for a raspberry pi hat. Monitors push button and turns on/off power. 8 channels of ADC available and some connectors for other peripherals. Onboard CAN device and transceiver connected to the raspberry pi

It's a custom computer for indoor bikes to measure cadence, speed and power, store sessions, visualise ongoing statistics and replace non chargeable solutions

Hardware (schematics, PCB, BOM) for iot-risk-data-logger-nfc-samd21 project

Reverse engineered Raspberry Pi Compute Module 5

Open source Vaporizer KiCad schematics (requires DIY PCB layout, would love it if someone contributed a laid out PCB but there's no expectation of that here!)
