The PCB are good quality, I used them to some arduino projects and they are easy to work with, the extra components are also a good addition.

Came Next Day. Very fast as i ordered it late in day. Wonderfully packed in zip bags and flexible plastic. Which came in a Professional looking box. Im glad i took the time to look as it has alot of jumpers, pins and connectors. I was a little worried if the boards would fit what i needed. And Yes there was plenty to fit my project and more. Also excellent quality.

I wanted to learn how to solder and came across this deal. Just what I needed to practice.

Works well
