This is the ultimate IoT board with wired 100Mb Ethernet Interface, Bluetooth LE, WiFi, Remote control IR, and CAN connectivity. The board can operate with single LiPo backup battery like UPS as it has an internal LiPo battery charger (no step-up converter, so relays, CAN and USB power would not work over battery). Two relays allow you to switch power appliances on and off.
ESP32-EVB-EA and ESP32-EVB-EA-IND come with ESP32-WROOM-32UE and external antenna; ESP32-EVB and ESP32-EVB-EA work in the commercial temperature range 0-70C; ESP32-EVB-IND and ESP32-EVB-EA-IND are functionally identical, but have all components rated for operatng in the industrial temperature range -40+85C.
ESP32-EVB is originally designed by OLIMEX Ltd and a result of continual improvements.
