Adding cheap and simple solar power to our small outdoor projects (e.g. ESP32, ESP8266, Arduino Pro Mini) removes the need to save energy or recharge batteries. Today we will enhance a simple 50 cents Li-Ion charger board to do exactly that. I am a proud Patreon of @GreatScott!, @ElectroBOOM , @Electronoobs , @EEVblog , and others.
