IoT Connected (Electricity) Powermeter

Lipo battery charge, protection and 5V boost converter.

This Project provides an Arduino Library for the MAX77650 PMIC

This cutting-edge project employs autonomous driving technology to optimize warehouse operations. The AMR excels in navigating complex environments, avoiding obstacles, and improving efficiency using advanced SLAM and robust navigation.

Custom build for a motion-triggered, video-monitored squirrel feeder. Driven by an ESP32, connected to Home Assistant.
