Placa industrial dedicada com ESP32, interface Ethernet blindada e bornes RS-485
Original project

IIoT gateway for isolated machines

A gateway bridges equipment and systems that use different communication methods: it reads factory-floor data, organizes it and delivers it over local Ethernet to SCADA or MES platforms using OPC UA as the integration standard.

First time with the ESP32? Golden Hardware Tips

  1. First stepsA data USB cable is all you need. See what to get, the onboard LED for your first test and a hardware summary.
  2. Common problemsBoard not detected, upload errors, reboot loops and pins that do not work: the most common causes and how to fix them.
  3. Dangers5V on a pin, too much current, 110/220 V mains and lithium batteries: what burns the board and what can hurt you.

New: learn to develop firmware with AI

  1. Pick your AIOpen our Tool Matrix and choose the ideal ecosystem (Claude, GPT or Gemini) for your type of project.
  2. Use our promptCopy our Master Engineering Prompt to reduce the most common AI mistakes, such as memory lockups and blocking functions.
  3. Flash straight from the webPlug your ESP32 into the USB port and use our Web Flasher to load the generated code without installing any local IDE.

Modbus RTU over RS-485 on the ESP32

Read Modbus RTU registers on the ESP32 without a library: DE/RE control, CRC16, the 3.5-character silence between frames and 120-ohm termination.

Motor temperature and vibration monitoring with ESP32

Predictive maintenance node with MPU6050 and a Type K thermocouple: vibration RMS, MQTT telemetry and a mechanical trend becoming a useful SCADA alarm.

ESP32 sending data to SCADA and MES

SCADA does not want your JSON: it wants tags. Topic modeling, data quality, heartbeat and why the gateway timestamp is not enough.

ESP32 publishing data to Mosquitto

Step by step to connect an ESP32 to an Eclipse Mosquitto MQTT broker, handling authentication and JSON telemetry format.

MQTT with TLS on the ESP32: validate the broker certificate and stop using setInsecure

The setInsecure() example encrypts but accepts any server. Your own CA, Mosquitto on port 8883, NTP time, heap and the negative tests that prove validation works.

LoRa on the ESP32: long-range point-to-point communication, without LoRaWAN

Two Heltec WiFi LoRa 32 V2 boards talking across hundreds of meters: SF, bandwidth and time on air, what we measured in the lab, the antenna, crystal and ACK traps, and packet loss by sequence number.
