In this post we are talking about this handy little gadget called a 5V single-channel relay module. It is super useful for our microcontroller projects whether we are using Arduino, Raspberry Pi, or even the ESP8266/ESP32. Let us break it down together, what it is, how it works, and how we can connect it. Understanding […]
Newly Updated Circuit Projects:
500V, 20A MOSFET IRFP460 Datasheet, Pinouts
The IRFP460 MOSFET is an N-channel MOSFET. It is rated for a drain-source breakdown voltage of 500V and a continuous drain current of 20A. This MOSFET is a third-generation device designed with fast switching and low on-resistance in mind. Specifically, it has a maximum drain-source on-state resistance of 0.27 Ohms. Basically this IRFP460 MOSFET is […]
How to Connect Digital Ammeter, Voltmeter Modules M4430, M3430
In this post I will be talking about the Chinese M4430 digital ammeter, voltmeter module which is a really neat, compact digital meter that you can mount on a panel. Whats great about it is that it is designed to measure and show us both the DC voltage and the current at the same time. […]
Automotive Display LED-backlight Driver Circuit using LP8864-Q1
The LP8864-Q1 is this cool automotive high-efficiency LED driver that comes with a boost controller. Basically it is made to efficiently power the LEDs in your car. It has got these four high-precision current sinks that do something called phase shifting. What is neat is that this phase shifting automatically adjusts based on how many […]
Automotive Trailer Lights Interface Circuit
This article explains an original Automotive Trailer Interface Circuit, a testament to the creativity of our reader Mr. August Peterson, an avid electronics devotee. We are honored to share his design and express our sincere thanks for his contribution to our platform. Overview Modern vehicles have load sensing on their rear lights to detect faults […]
TPS24710/11/12/13 Hot-Swap Controller Circuit Explained
When we talk about hot-swap controllers, it is basically an electronic device or integrated circuit (IC) that allows you to the insert or/and remove circuit boards, modules or parts within an active system without having you to switch off the system. It regulates the surge current whenever a component is installed and protects from short […]
