This firmware turns an ESP32 board with an 8-relay module into a robust, network-controlled device using the Modbus TCP protocol. It provides a comprehensive interface for direct manual control, ...

Hey, i am using a ESP32-C with a MAX485 converter. I want to read the existing modbus communication between my heat pump and its controller. I am trying to reverse engineer the modbus protocol ...

We just got our hands on some engineering pre-samples of the ESP32-C3 chip and modules, and there’s a lot to like about this chip. The question is what should you compare this to; is it more an ESP32 ...

Waveshare ESP32-P4-NANO is the first third-party ESP32-P4 RISC-V board we’ve seen and it follows the launch of the Espressif Systems’ ESP32-P4-Function-EV-Board devkit introduced this summer. While ...

The Modbus protocol is widely used in the industrial sector for communication between systems and controllers. This is usually done with the tried-and-true RS485 interface and conventional copper wire ...

In a recent article in Elektor magazine, [Clemens Valens] describes the construction and software for an ESP32 walkie-talkie system that uses ESP-NOW for the wireless connection between units, along ...

This ESP32 project is an exciting and interactive way to control LEDs using hand gestures. We will use an ESP32 board, Python, MediaPipe, and OpenCV to create a system that can detect specific hand ...
