User manual for the Olimex ESP32-EVB development board featuring ESP32-WROOM-32E/UE modules, Ethernet, CAN bus, dual relays, and LiPo charging support.
The ESP32-EVB is an open-source development board from Olimex based on the Espressif ESP32-WROOM-32E or ESP32-WROOM-32UE modules. This hardware platform integrates 10/100Mbps Ethernet via the Microchip ETH8710A, dual 10A/250VAC relays, and a CAN bus interface using the SIT1050T transceiver. It includes an on-board CH340T for USB-to-serial programming, a MicroSD slot, and IR communication. Power is managed by the Silergy SY8089 regulator and a Microchip MCP73833 LiPo charger for battery-backed operation. The manual provides details on hardware layout, power consumption, pinout descriptions, and software setup for Arduino and ESP-IDF environments.
