Prototypes ----------- * Prototype 1: - Manufactured at ETSIT UPM University (Madrid, Spain) - Only two layers: bottom and top layers (No silkscreens). - Version for findings "bugs" - As this is a prototype manufactured in Spain, the notes are in Spanish * Prototype 2: - Manufactured at pcbcart.com. This manufacturer told us to modify the board because there were some tracks near the edges. We removed some tracks and re-route the tracks... but we forgot to route one track!!! Therefore this board has a bug :-( The manufacturer creates a panel of 10 boards. * Prototype 3 (bugs-fixed) -This is a bug-fix release. It has not really been manufactured. It is similar to prototype 2 but with the bug fixed (and no panel). IF YOU ARE PLANNING TO MANUFACTURE THIS BOARD, YOU SHOULD USE THE GERBER FILES OF THE PROTOTYPE 3
