With the prevalence of USB devices, it might be easy to mix up USB headers and ports, but there is a key difference between ...

On page 4, there is an "IDE Power" connector. It looks a lot like a 4 pin CPU fan connector, but it (obviously) provides different voltages that are appropriate for 3.5" IDE drives (5V, 12V) and the ...

I’m a big proponent of DIY PC building and I tend to describe it as “relatively straightforward.” For the most part, everything just plugs in where it should. But there is one aspect of putting ...

The motherboard takes a full-size 24-pin ATX power link from the power supply, which handles most functions on the PC. Still, ...

Building a PC isn’t easy for everyone, but if you’re someone who’s planning on doing it soon or just a PC enthusiast who’s passionate about PCMR, then this is the perfect blog for you. In this column, ...

We all like to standardise. But there doesn’t appear to be any pin number system defined for one of the most popular wire-to-board connector sets. Marking the PCB pin header isn’t so important, as the ...

I2C is a wonderful interface. With four wires and only two GPIOs, you can connect a whole lot of sensors and devices – in parallel, at that! You will see I2C used basically everywhere, in every phone, ...

[John] wrote in with a solution to a prototyping issue that has vexed us for quite some time. Above you can see the DIP friendly solution for dual-row pin headers which he came up with. With just a ...
