Review on PJRC Teensy 2 0 by David Pearson

First of all, this board is easy to work with. It even has two points for ground and VCC, making it easy to raise and lower the point when you need it. Also, programming couldn't be simpler. Push the button and program, done. It's that easy. I would highly recommend them and will likely get more for other projects in the future. I've used mine to convert IBM XT protocol keyboards over USB and it worked great for the job.
