Lexin original ESP32 module, a large number of stock, directly photographed, the same day delivery.

. 1 ESP32  integrated 2.4 GHz Wi-Fi  and Bluetooth dual-mode single-chip solution, TSMC ( TSMC ) ultra-low-power 40  -nm process, with

Optimal power performance, RF performance, stability, versatility and reliability for a wide range of applications and power consumption needs.

ESP32 is  designed for mobile devices, wearable electronics and Internet of Things ( IoT ) applications. As the industry's leading low power chip, ESP32  has

Fine-resolution features such as clock gating, power-saving modes, and dynamic voltage scaling.

     For example, in a low-power IoT  sensor Hub  application scenario, ESP32  will only be periodically woken up under certain conditions. Low duty cycle can make

. 3 ESP32  energy consumption of the chip is minimized. The output power of the RF power amplifier can also be adjusted to achieve the most communication distance, data rate and power consumption.

Good balance.
