DFRobot Edge101 Industrial ESP32 with RS485 - CAN - Ethernet

The DFRobot Edge101 is an industrial IoT controller with ESP32 in a metal housing. Besides 2.4 GHz Wi-Fi and Bluetooth it has isolated RS485, isolated CAN bus and 10/100 Mbit/s Ethernet. It is powered with 9 to 26 V DC via the plug-in terminal or with 5 V via USB-C, protected against reverse polarity, surges and ESD. It is programmed with the Arduino IDE or ESP-IDF and mounted on a DIN rail or with brackets on the wall.
