Solderless Breadboard Assortment Kit: The kit contains 140 components inside a breadboard to help you complete electrical experiments or tests. Easy to use: The holes on the test plate are connected with each other through the metal strips inside the plate. You can insert electronic components into the holes on the test board and connect them with jumpers. High quality: All components in the kit have been carefully selected to meet the highest standards of quality and performance. Widely applications: The breadboard kit can be used by amateurs, students and professionals in electronics, robotics and other fields to prototype and test electronic circuits, and can also be used for DIY production or various circuit experiments. Note: Breadboard has strips of metal underneath the board and connect the holes on the top of the board. The top and bottom rows of holes are connected horizontally and split in the middle while the remaining holes are connected vertically. Specifications:
