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.
  • On-board programmer, CH340T USB-to-UART
  • WiFi, Bluetooth LE connectivity.
  • 100Mbit/s Ethernet interface, Microchip LAN8710A PHY.
  • MicroSD card slot.
  • 2 x 10A/250VAC (15A/120VAC 15A/24VDC) relays with connectors and status LEDs.
  • CAN interface, Microchip MCP2562-E high-speed CAN transceiver.
  • IR receiver and transmitter, up to 5 meters distance.
  • BL4054B LiPo battery charger with status LEDs for stand-alone operation during power outages.
  • Power jack for external 5VDC power supply.
  • Universal EXTension (UEXT) connector for connecting UEXT modules.
  • User push button.
  • 40 pin GPIO connector with all ESP32 pins.
