Espressif ESP32 Overview

The ESP32 from Espressif is a powerful SOC (System On a Chip) which gives not only up to 240Mhz of processing power, but also full Wifi in AP/STA modes, Bluetooth Low Energy, SPI, UART, I2S, I2C and more, all in an Arduino compatible chip.

There are a wide variety of modules and boards which are now available with an ESP32 on board, allowing you to select the most suitable base hardware for your project, to get you moving as quickly as possible, from tiny Wifi and BLE boards such as the PICO and TinyPICO, to the ESP-32CAM, and so many more!

The ESP32 also has certification when purchased directly from Espressif allowing you to build real products on this without worrying about the CE/UL certification elements, so if you want to fully integrate the SOC into your own board, there is plenty of advice available.
