The ESP32 is a versatile 2.4 GHz Wi-Fi and Bluetooth combo chip built using TSMC’s ultra-low-power 40 nm technology, optimized for power efficiency, RF performance, and reliability in various applications.

Designed for low-power use, it features fine-grained clock gating, multiple power modes, and dynamic power scaling, minimizing energy consumption through low duty cycles. The power amplifier output is adjustable, allowing a balance between range, data rate, and power consumption. With integrated antenna switches, power amplifiers, low-noise receive amplifiers, and power management, the ESP32 offers high functionality for IoT applications with minimal PCB requirements.
