DFRobot Edge101 Industrial ESP32 with RS485 - CAN - Ethernet

The DFRobot EdgeIoT Controller is an industrial-grade IoT controller based on the ESP32, ideal for automated controls and edge applications. It features a compact, DIN rail-compatible enclosure and combines digital inputs and outputs, serial interfaces, and networking options for versatile communication. The integrated ESP32-D0WDQ6 SoC supports dual-core operation at 240 MHz, Wi-Fi 2.4 GHz, and Bluetooth 4.2 BLE. The device offers 4 digital inputs (12–24 V), 4 relay outputs (250 V AC / 5 A), RS485, CAN bus, UART, and an RJ45 interface for Ethernet. An integrated RTC, TF card slot, watchdog timer, and 16 MB flash make the system robust and standalone. Thanks to Grove port support, additional sensors can be quickly connected. Ideal for applications such as building automation, energy monitoring, production supervision, or remote maintenance. Programming is done via Arduino or ESP-IDF.
