Engineered for easy assembly and broad compatibility, this adapter is a must-have for any serious Pi tinkerer looking to maximize connectivity.

## Description

Description:GPIO Edge Extension is a module that leads the 40Pin GPIO pins of the Raspberry Pi out of convenient use. Features:Easy to assemble Vertical Pin header Horizontal Pin header Package Includes:1 x GPIO Edge Extension Technology support:https://wiki.52pi.com/index.php/GPIO_Edge_Extension_SKU:_EP-0121

Review: Great breakout - Really useful for having a breakout when you already have a hat. Fitted this so I could add a button and have a hat fitted.
Review: When you need this, you really need it - I can't imagine that this device has many applications; but it's the kind of thing that, when you need it, you really need it. In my case, I had a Pi sandwiched between two other boards, and I needed to bring out the GPIO headers. There was no easy way to do that with a regular cable, because there just wasn't space. But, with this, I could connect the GPIO cable to the outward-facing set of pins, and that worked fine. The device is well made and, most importantly in my case, is only a tiny bit wider than a standard 40-way cable. This matters because the device has to fit between the Pi mounting pillars, which are only a millimetre or so separated from the GPIO header block. Had this device been even 3mm wider, it wouldn't have fit. So, exactly what I needed. Whether I'll ever need one again, I'm not sure. But I'm glad it was available.
