DFRobot DFR0886 Edge101 ESP32 IoT Programmable Controller

DFRobot DFR0886 Edge101 Industrial ESP32 Internet of Things (IoT) Programmable Controller is a rugged, industrial‑grade control platform designed to bridge the gap between traditional ESP32 development boards and real‑world deployment needs. Powered by an ESP32 dual‑core processor, the DFRobot DFR0886 integrates essential industrial communication interfaces [including isolated RS485 (Modbus‑compatible), isolated CAN bus, Ethernet, Wi‑Fi^®, and BLUETOOTH^®], making the controller exceptionally well‑suited for automation, monitoring, and IoT system integration.

Housed in a durable metal enclosure, the Edge101 provides comprehensive protection features such as electrical isolation, anti‑static safeguards, lightning protection, overvoltage protection, and reverse‑polarity protection, ensuring stable operation in harsh environments with a wide 9V_DC to 26V_DC supply range. The controller offers eleven native GPIOs, three I²C interfaces, a TF card slot for data storage, and a PCIe expansion slot for optional 4G LTE modules, enabling flexible connectivity and expansion.

The DFRobot DFR0886s support for both ESP32 and Arduino ecosystems allows developers to move smoothly from prototyping to deployment while maintaining a familiar development experience. These combined features make the Edge101 a versatile solution for applications such as industrial automation, edge computing, Modbus gateways, CAN bus nodes, and remote environmental or asset monitoring.
