Hi, I'm Bill. I'm a software developer with a passion for making and electronics. I do a lot of things and here is where I document my learning in order to be able to inspire other people to make ...

LILYGO T-Connect Pro is a DIN rail-mountable, ESP32-S3-based industrial IoT controller with Ethernet, WiFi 4, Bluetooth 5.0 LE, and LoRa connectivity, as well as CAN Bus, RS232, and RS485 interfaces.

Electronica: Arduino makes single-pair Ethernet accessible, and RS485 too Arduino announced a single-pair Ethernet adapter board for its Uno R4 single-board microcontroller at Electronica this morning ...

Arduino announced a single-pair Ethernet adapter board for its Uno R4 single-board microcontroller at Electronica this morning. Microchip participated in the development – its LAN8651B1T-E/LMX single ...

This code is used to get the data from the CVM NRG96 energy meter manufactured by CIRCUTOR Ltd, to Arduino UNO development board. Here, we are using the MODBUS RS485 protocol for comminication between ...

The P1AM-SERIAL is an industrial rated shield that provides two serial interfaces individually configurable for RS232 or RS485. The P1AM-SERIAL is ideal for communicating with RS232 and RS485 devices ...

LILYGO T-RSC3 is a relatively compact ESP32-C3 board with WiFi 4 and Bluetooth LE 5.0 connectivity, support for RS232 and RS485 communication protocols through a DB9 connector and a terminal connector ...

In a recent post we interfaced a small DMX RGB LED Par Light with an Arduino Uno through a MAX485 module. In this post we will learn how to work with a compact USB to RS-485 Converter Module. This ...

In this tutorial Master STM32F103C8 has three push buttons that are used to control the status of three LEDs present at the Slave Arduino Uno by using RS-485 Serial communication.
