 ESP32 is a low-cost, low-power system on a chip (SoC) series microcontroller with WiFi & dual-mode Bluetooth capabilities ((https://www.espressif.com)). ESP32 SoC is highly integrated with built-in antenna switches, power amplifiers, low-noise receive amplifiers, filters, and power management modules. Inside all families of ESP32, there is a single-core or dual-core Tensilica Xtensa LX6 microprocessor with a clock rate of up to 240 MHz.  ESP32 is designed for mobile, wearable electronics, and Internet-of-Things (IoT) applications. It features all the state-of-the-art characteristics of low-power chips, including fine-grained clock gating,  multiple power modes, and dynamic power scaling.  ESP32 is a low-cost, low-power system on a chip (SoC) series microcontroller with WiFi & dual-mode Bluetooth capabilities ((https://www.espressif.com)).
