Keyestudio Proto Shield is particularly designed for the Arduino UNO R3. 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 spaced through-holes, giving enough port resources.
You can even stick a mini 170-holes breadboard (included) on the prototyping area. You can weld elements on the shield directly or connect circuits with the mini breadboard.
