Original ESP32-WROOM-32D 2.4GHz WiFi + Bluetooth Module MCU For Development Board  

ESP32 Module Description:

ESP32 is a single-chip solution integrating 2.4 GHz Wi-Fi and Bluetooth dual mode. Adopting 40nm process, it features excellent power consumption performance, RF performance, stability, versatility and reliability. It is suitable for a variety of applications and different power requirements.

It is designed for mobile devices, wearable electronics, and Internet of Things (IoT) applications. As an industry-leading low-power chip, the ESP32 has features such as fine-resolution clock gating, power-saving modes, and dynamic voltage adjustment. For example, in the low-power IoT sensor Hub application scenario, ESP32 will be awakened periodically only under certain conditions. It features low duty cycle.

The energy consumption of the ESP32 chip is minimal. The output power of the RF power amplifier is adjustable to make a balance among communications distance, data rate and power consumption.
