The ESP32 is a dual core Tensilica LX6 microcontroller with 520 KB SRAM, integrated Wifi, Bluetooth, and more. Espruino is a very light weight JavaScript interpreter that runs on the ESP32, and other microcontrollers.
This documentation is intended for those who want to run JavaScript on any ESP32 microcontrollers. It will describe how to flash the ESP32 with the latest firmware, connect to Wifi and get the other pins going.
