We’ve previously covered the EdgeBox-RPi4 industrial controller powered by a Raspberry Pi Compute Module 4 and plenty of I/Os such as RS485, RS232, digital inputs and outputs, and connectivity options such as Gigabit Ethernet, WiFi 5, Bluetooth 5, and 4G LTE.
But if you don’t quite need the power of a Linux controller, the EdgeBox-ESP-100 industrial edge controller based on an ESP32-S3 dual-core WiFi and Bluetooth microcontroller and offering a similar set of features, albeit with twists, may be an interesting option.
The EdgeBox-ESP-100 can be programmed with the ESP-IDF framework, but Seeed Studio is also working on support for IEC 61131-3 compliant programs namely Codesys expected in Q2 2023, and the free-to-use and open-source OpenPLC PLC suite. Documentation is currently limited to a product brief and a user manual describing the hardware both shared via the shopping page (see below).
Typical applications include SCADA, industrial controllers, PID control loops, logic sequencing control, and industrial gateways. While the EdgeBox-ESP100 looks similar to the EdgeBox-RPi4, there are notable differences as illustrated in the table below which also features the EdgeLogix-RPI-1000 with an integrated touchscreen display and additional I/Os.
The EdgeBox-ESP-100 ESP32-S3 industrial edge controller can be purchased on Seeed Studio for $179 plus shipping.
