The latest Arduino MEGA protoshield V3 is produced with PCB metallurgical deposition processing and its golden square mainboard with smal SMT components encapsulation make the operating more easier for the l pad spacing make welding components more convenient; Its SOP28 Arduino electronic enthusiasts and make them be bound by the straightly inserted elements. This board not only can be seamlessly inserted on the Arduino MEGA controller and welded directly to the component to finish all kinds of prototype circuits. And you can also paste the Mini bread plate and finish various circuit experiment, board integrating power light, resetting button by jumping colorful line. Arduino MEGA Protoshield V3 is the best choice for you to study Arduino MEGA controllers. PCB with first-class metallurgical deposition processing Distribute with white bread board, making you do experiments relaxedly.
