This item requires soldering 16 headers, and adding the extra 5 is useful for connecting it to a breadboard or controller.
The soldering should be manageable for anyone with a usable soldering iron and at least a tiny amount of soldering experience. Instructions are available on the AdaFruit site.
That's where the tricky bit ends.
If you're using an Arduino (or compatible), just plug it in and use the provided library (also from the AdaFruit website) to control it quickly and simply. Functions are provided for displaying numbers and times, right through to complete control of each segment if you want to, and it's all demonstrated in the example sketch.
It's bright enough for most situations and the brightness is adjustable too.
My only two slight gripes are:
1) It looks great in lower light, but when it's under something brighter, the segments which are off (white) contrast almost as much with the dark grey background as the ones which are on (red), which can make it tricky to read at a glance. I fix this by putting a blank piece of paper over it - the red shines through bright and clear.
2) It's a definite time saver compared to writing code to control and illuminate all 32 controllable segments separately (and getting that code to run alongside whatever else your controller is doing), but if this is a challenge you'd enjoy, and depending on how you value your time, the convenience may not be worth almost £20 - the displays without backpacks are a lot, lot cheaper.
I'd recommend it to anyone who's willing to pay for it.

Wanted a larger display that could be seen from a few feet away. It can actually be seen from much further away and seems much larger than it's 1.2" digit height indicates.Connected to my arduino.

Bought this for a timing project, no issues with construction.Programming was exceptionally easy and worked first time.Makes hard wiring a regular 7 segment display a thing of the 20th century Easily visble from at least 7 metres away and the brightn
