Baliza S.O.S seguridad vial
This is my first PCB project. It's amazing reciver the PCB like I did desing. Here the post in my blog where I explain how to mount this project with 3d printing parts and arduino mini pro: http://akirasan.net/baliza-vial-sos/ The quality of the PCB is great. The next time I'm going to make a different shape, no more squares ;)
