Description
Energy saving
The ESP32 is a chip designed with TSMC technology for extremely low power consumption (ultra-low power management), allowing for the best power and performance with its high efficiency.
As the quiescent current of the ESP32 chip is less than 5 μA it is particularly suitable for use with batteries or rechargeable batteries
Compatible
It has a similar pin layout to the conventional Mini ESP8266-12F and is therefore pin-compatible with most accessories for it.
