D-FLIFE ESP32 D1 Mini NodeMCU ESP-WROOM-32 WLAN WiFi Bluetooth IoT Development Board 5V Compatible with Arduino -2pcs-

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 ?A it is particularly suitable for use with batteries or rechargeable batteries Compatible It has a similar pin layout to the conventional D1 Mini ESP8266-12F and is therefore pin-compatible with most accessories for it.
