This design idea outlines a method to use an analogue switch and discrete components to reduce the power dissipated in relay actuation. Presented here is an MAX4624-based circuit to drive a 5V relay ...

Jetson Orin Nanoでリレーモジュールを動かしたいのに、GPIOをつないでも反応しない／動作が不安定といったトラブルに遭遇した方も多いのではないでしょうか？ 私もまさにそうでした。しかし、トランジスタと外部電源を組み合わせることで安定動作に成功。

This project is an advanced 4-channel relay module designed for home automation and IoT applications. Unlike standard relay boards, this design integrates an LM2596 buck converter for onboard ...

Following up my previous post entitled “DIY Modular Stripboard / Perfboard Casing for Raspberry Pi (Part 1)” where I explained how I created an modular enclosure made of perfboard, or the overall ...

The DR44 is a two wire Alternator with a built-in regulator. Well, really three wire but the third wire is not needed if adapting this alternator into another vehicle. The DR44 needs a 5V, 128Hz PWM ...

The main usage of the Relay was seen in the history of transmitting and receiving the information, that was called as Morse code where the input signals used to be either 1 or 0, these change in ...

Remove D2 from relay main board Remove C5 from relay main board Connect FT231X K3 pin 2 (or K2 pin 4) to R4 on relay main board Connect FT231X K3 pin 3 (or K2 pin 5) to R3 on relay main board Connect ...
