<b>Introduction:</b><br> Keyestudio ProtoShield is particularly designed for the MEGA 2560. It makes it easy for you to design custom circuits and solder electronics directly on it. For convenient use, there is a large prototyping space of both connected and unconnected spaced through-holes on the shield. There is also a soldering position reserved for SMD chip on the protoshield. You can easily solder SMD ICs on the prototyping area to test them with your Arduino board. It also extends out a row of power and ground through-holes, giving enough port resources. You can even stick a tiny 170-holes breadboard (included) on the prototyping area. You can weld elements on the shield directly or connect circuits with tiny breadboard.<br><br> <b>Controllers Compatible:</b><br> keyestudio MEGA 2560 R3<br> Arduino MEGA 2560 R3<br> Technical Details<br> Dimensions: 106mm x 56mm x 19mm<br> Weight (only MEGA protoshield): 27.2g
