The motherboard takes a full-size 24-pin ATX power link from the power supply, which handles most functions on the PC. Still, there's also a dedicated central processing unit (CPU) connection, usually ...

Parallel ATA (IDE) uses 40 pins, not 26. 26 was for floppies. But it's a standard 40-pin "header" connector. Sometimes called "IDC". CF cards have the PATA interface on a 50-pin connector. I don't ...

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 ...

Given an unknown PCBA with an ARM processor, odds are good that it will have either the standard 10 pin 0.05″ or 20 pin 0.1″ debug connector. This uncommon commonality is a boon for an exploring ...

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 ...

If you’ve ever opened a PC case and stared inside, or looked at a bare motherboard, you may be taken aback by the number and variety of connectors, pins, and slots that exist on a modern PC ...

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, ...

TE Connectivity (TE) introduces new wire-to-board headers as part of its Power Triple Lock connector product line; thereby expanding the family of connectors targeting appliances into a growing number ...
