The scenario
Designing a solar-powered IoT node with an ESP32 that requires battery charging and monitoring.
What is in this drawing
Read the decisions behind it.
01
Use a TP4056 charger IC for Li-ion charging
02
Voltage divider to measure battery voltage with ESP32 ADC
03
Schottky diode for reverse polarity protection from solar panel
When building any solar-powered microcontroller project that needs battery management and voltage monitoring.
