other | ProtoShield Robot Prototype Extension Board Support UNO R3 Mini Breadboard Learning Development Board

The ProtoShield prototype extension board used by Arduino Duemilanove is used to build circuit prototypes. Components can be directly soldered on the board, or circuits can be connected through the mini breadboard above. The bread board and the circuit board are connected by double-sided adhesive tape, and the bread board and the circuit board are separated when sold.The ProtoShield prototype expansion board has two LEDs and two button circuits, which can be used directly. All pins and power supplies have been extracted. It is very suitable for working with Arduino to build a circuit prototype.
