Keyestudio MEGA Protoshield/prototype expansion board V3 for Arduino+breadboard

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.
