A Peek into the ESP32-S3 module-powered Industrial Edge Controller

A Peek into the ESP32-S3 module-powered Industrial Edge Controller


EdgeBox-ESP-100 is an industrial-grade controller with a rugged architecture. It features an ESP32-S3 SoC. SeeedStudio’s latest release includes features for communicating with Fieldbus solutions, including CAN Bus, RS485, Ethernet LAN port, and other isolated peripherals. The EdgeBox-ESP-100 differs from previous SeeedStudio Edge Series products (such as the EdgeBox-RPi-200/1000) in that it incorporates the ESP32 SoC described below.

  • It has an Xtensa 32-bit LX7 dual-core (up to 240MHz), along with 512KB + 8MB RAM, 16 MB Flash storage, and 2.4GHz Wi-Fi/BLE 5.0.

The datasheet says that this device already has a 4G LTE cellular module installed (A7670G SIMCom). The EdgeBox-ESP-100 can be changed to support LoRaWAN, but this will mean that the 4G LTE module will have to be removed.

As you can see in the picture below, the EdgeBox-ESP-100 has a phoenix connector that gives you access to isolated I/Os like 4x digital inputs, 4x analog inputs, 6x digital outputs, and 2x analog outputs.

The EdgeBox-ESP-100 can take power from 10.8V to 36V. Also, the EdgeBox-ESP-100 can work at temperatures between -20°C and 60°C. Since it is based on an ESP32 module, this industrial-embedded device can also be programmed with ESP-IDF. The STM32H747XI Dual ARM Cortex processor runs the  Arduino Opta Wi-Fi, which came out a few months ago and has similar features.

SeeedStudio seems to offer a 2-year warranty, and they said this product is compliant with RoHS, CE, FCC, UKCA, and TELEC. The product is not yet compliant with IEC 61131-3; for now, its status is “under development.”

The EdgeBox-ESP-100 can be bought on SeeedStudio.com for $179.00. Read the SeeedStudio blog post to find out more about the EdgeBox-ESP-100 and other Edge Series products.
