Overview
********

The Olimex ESP32-EVB is an OSHW certified, open-source IoT board based on the
Espressif ESP32-WROOM-32E/UE module. It has a wired 100Mbit/s Ethernet Interface,
Bluetooth LE, WiFi, infrared remote control, and CAN connectivity. Two relays
allows switching power appliances on and off.

The board can operate from a single LiPo backup battery as it has an internal
LiPo battery charger. There is no step-up converter, so relays, CAN, and USB
power does not work when running off battery.

Hardware
********

- ESP32-WROOM-32E/UE module with 4MB flash.
