The EdgeBox-ESP-100 is a rugged controller equipped with the ESP32-S3 SoC. This new product from SeeedStudio offers support for fieldbus solutions as 1x CAN Bus, 1x RS485. Ethernet LAN port, and other isolated peripherals.

Unlike other SeeedStudio products from the Edge Series (i.e. EdgeBox-RPi-200/1000), the EdgeBox-ESP-100 integrates the following ESP32 SoC. 

• ESP32-S3 – Xtensa 32-bit LX7 dual core (up to 240MHz); 512KB + 8MB RAM; 16 MB Flash storage; 2.4GHz Wi-Fi/BLE 5.0

According to the datasheet, this device includes a pre-installed 4G LTE cellular module (A7670G SIMCom). The EdgeBox-ESP-100 can be customized to support LoRaWAN as well, although it will replace the 4G LTE module.

As shown in the image below, the EdgeBox-ESP-100 features a phoenix connector providing access to isolated I/Os such as 4x digital inputs, 4x analog inputs, 6x digital outputs and 2x analog outputs.

The EdgeBox-ESP-100 accepts 10.8V to 36V power input. Additionally, the EdgeBox-ESP-100 operating temperature ranges from -20°C to 60 °C.

This industrial embedded device can also be programmed with ESP-IDF since it’s based on a ESP32 module. Another product that offers similar features unveiled a few months ago is the Arduino Opta Wi-Fi powered by the STM32H747XI Dual ARM Cortex processor.
