Seeed Studio EdgeBox-ESP-100-Industrial Edge Controller is a lightweight yet powerful Industrial IoT controller designed for field automation and edge computing. With integrated multi-wireless capabilities and multi-Fieldbus support, it can operate independently as a PLC or serve as an industrial gateway to connect legacy PLCs to modern networks and cloud platforms. Powered by Raspberry Pi CM4, the EdgeBox-ESP-100 offers 3×RS485, dual Ethernet ports, and optional wireless connectivity including 4G LTE, LoRa, Wi-Fi/BLE, and Zigbee. This makes it a versatile solution for Industrial IoT deployments requiring reliable communication and flexible integration. Important Notice: USB Programming/Debug Function AvailabilityThe USB Programming/Debug function is only available on the latest version of the EdgeBox-ESP-100. Older versions only support power supply through the USB-A port and do not support programming/debugging. Do Not Connect the USB-A Port of Older Versions to a PCConnecting the USB-A port of older models to a PC may cause improper behavior. Please use only the new version if you intend to program or debug via USB.
