Edgebox-ESP-100

EdgeBox-ESP-100 is an ESP32-based controller designed for lightweight automation solutions. It supports analog input, effectively monitoring and controlling in a remote environment, ideal for PID control loops, logic sequencing control, or a gateway with flexible wireless and field sensors expansion.

Besides EdgeBox-ESP-100, We also have the other 2 Edge products for different solutions in the Edge family, powered by Raspberry Pi. To help you understand the differences deeply and choose the most suitable part for your projects, please refer to the Seeed Studio Edge Series Page.

It offers isolated CAN, RS485 Fieldbus connections, and rich IO resources for extensive facilities and sensors input, for both digital and analog signals. It is perfectly satisfactory to the PLC and field automation applications.

Since it contains on-chip Wi-Fi and BLE functions, and also includes a 4G LTE module Cellular, EdgeBox-ESP-100 can be utilized to establish an industrial gateway, enabling the original PLC to connect the network or cloud.

This portable box comes with rugged hardware, an electrical design, and an aluminum alloy enclosure, by which it maintains its function in a wide temperature range and provides high surge and short circuit protection, for diverse deployment methods based on your business.

Features

  • Multi-Fieldbus Support: CAN, RS485, Ethernet
  • Multi-wireless Capability: On-chip Wifi, BLE connectivity; built-in Cellular 4G LTE module
  • Reliable Hardware Design: Rugged, maintenance-reduced structure
  • Reliable Electrical Design: High isolation, High surge, and short circuit protection
  • IEC 61131-3 compliant programs support (under development)
  • Programmable with ESP-IDF, Arduino

  pinMode(DO0, OUTPUT);
  pinMode(DO1, OUTPUT);
  pinMode(DO2, OUTPUT);
  pinMode(DO3, OUTPUT);
  //setup DO pins default to Logic LOW
  digitalWrite(DO0, LOW);
  digitalWrite(DO1, LOW);
  digitalWrite(DO2, LOW);
  digitalWrite(DO3, LOW);
}

void loop() {
  //Switch on DO0 and Swith off DO3
  digitalWrite(DO0, HIGH);
  digitalWrite(DO3, LOW);
  delay(2000);
