ProtoShield Expansion Board with Mini Breadboard 170 Holes

Arduino ProtoShield prototype expansion board with mini breadboard
The ProtoShield prototype expansion board used with the Arduino Duemilanove is used to build a circuit prototype. You can solder components directly on the board or connect the circuit through the mini breadboard above. The breadboard and the circuit board are connected by double-sided tape, and the breadboard 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 have been drawn out, which is very suitable for building circuit prototypes with Arduino.
