Olimex ESP32-EVB Development Board

This is the ultimate ESP32 IoT board with a wired 100Mb Ethernet Interface, Bluetooth LE, WiFi, Remote control IR and CAN connectivity!

The board can operate with a single

LiPo backup battery

(like a UPS) and has an internal LiPo battery charger (there is no step-up converter though, so relays, CAN and USB power will not work over battery).

The two onboard relays allow you to switch power appliances on and off rated to 10A/250VAC (15A/120VAC 15A/24VDC) with status LEDs for visual feedback.

The board can be powered via a robust barrel jack (5V DC), or via Micro-USB (including programming). A number of

demo software files are available on GitHub

.
