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.

Hardware source (KiCad) from my master's thesis in telecommunications engineering at the Polytechnic University of Valencia, 2025.

🌏 Detecting seismic wave using 3 geophones and 3-axis accelerometer, pack & send data to AnyShake Observer over RS232 / RS485 serial.

Three-Phase Energy Monitor (3P4W) with RJ45 Ethernet communication, powered via PoE and based on the ESP32-S3. Designed for the real-time acquisition and visualization of electrical parameters in 4-wire systems within Office Blocks.

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.

Tokay AI Camera - ESP32 camera development board

Domestic vibration sensor with ESP32: detects and monitors motion and vibrations in real-time using a 6-axis MPU-6050 IMU. Battery-powered and Wi-Fi/Bluetooth enabled, ideal for smart home, IoT, and predictive maintenance applications.

A modular device designed to test electrical cables. It supports testing of both short cables (both ends accessible) and long cables (with ends far apart). The device visually indicates conductor continuity using LEDs.
