ESP32

"The ESP32 is a low cost, low power microcontroller with integrated Wi-Fi & dual-mode Bluetooth, which employs a dual-core Tensilica Xtensa LX6 microprocessor. ESP32 is created and developed by Espressif Systems, a Shanghai-based Chinese company, and is manufactured by TSMC using their 40 nm process.^[1] It is a successor to the ESP8266 microcontroller.

Features of the ESP32 include the following:^[2]
