TE Connectivity’s Matt McAlonis discusses how engineers can use the “follow-the-wire” approach to enhance connectivity in ...

not sure if this is the right place to ask a question, but I saw a lot of examples and maybe someone had a similar issue/project. I have bought the display (USB-C version) and I want to build a simple ...

Let’s keep with the schematic style – add two more connectors, one 5-pin and one 7-pin, rearrange the pinout, and keep them in their own nicely delineated area.

Those aren’t here. Next, a 5V relay is wired between the output of the timer chip and the ground rail, which runs on 5VDC. When the timer output is high, it will typically be somewhere between 1.2V ...

In this blog, we will explore how a relay works, how to interface a single-channel relay with an Arduino Uno, and demonstrate a simple example of how to use the 5v relay module to control a lamp.

Welcome to my quick review of an inexpensive 2-channel 5V relay module controlled via RS485 bus utilizing Modbus RTU protocol. As claimed by some online sellers, this easy-to-get Modbus RTU 2-Channel ...

Chaz Andrew, Technical Manager at Doepke considers how different types of residual current can impact on RCD performance and the reasons behind the requirements of regulation 531.3.3 proposed in the ...

The board ships with one LTE antenna, one GPS antenna, a 2-wire cable with a JST connector for an external battery, and two pin headers. LILYGO provides documentation and code samples for Arduino and ...

LilyGo T-Relay-8 is an ESP32 WiFi & BLE board equipped with eight 5V relays supporting up to 250V AC or 28V DC, as well as 16-pin GPIO header for expansion. The board offers a more compact solution ...
