Micro USB Type Interface Power Adapter Board 5V line Module, Female Micro USB to DIP 5 pin Board 2.54mm (12 Packs)

There isn't much room for messing the design of a product like this, but, it's not impossible. They could have made the modules gigantic or even too small so you couldn't solder to them. And, for all that there's very little that could go wrong, there's also very little that can go right. There's not much room for improvement either. I will give them credit though. They did do everything right that can be done right. The board is easy to work with and the terminals are presoldered so you don't have to use flux or anything. They also gave it two small screwholes that can help to screw it into place where possible. They also included header pins for connecting via cable but didn't put them in so you don't have to use them if you don't need them (for which I am grateful because I don't.)Overall you're not going to get much difference picking a different one, but these are a great price and do what they do quite well with no real room for complaint.
