ESP32 is a single 2.4 GHz Wi-Fi-and-Bluetooth combo chip designed with the TSMC ultra-low-power 40 nm technology. It is designed to achieve the best power and RF performance, versatility, and reliability in a wide variety of applications and power scenarios.
Ideal for low-power applications, the ESP32 SoC features fine-grained clock gating, multiple power modes, and dynamic power scaling. A low duty cycle is used to minimize the amount of energy that the ESP32 SoC expends. The output of the power amplifier is also adjustable, thus contributing to an optimal trade-off between communication range, data rate, and power consumption. The ESP32 SoC is highly-integrated with in-built antenna switches, power amplifiers, low-noise receive amplifiers, and power management modules. ESP32 adds priceless functionality and versatility to IoT applications with minimal Printed Circuit Board (PCB) requirements.
