Proto Shield prototype extension boards, used to build the circuit prototypes directly on the board welding components, mini bread plate above can also be connected to the circuit. Sided adhesive connection between the bread board and the board, bread board and the circuit board is sold separate.

The Proto Shield prototype expansion board with two LEDs and two buttons circuit, can be used directly, pin and power have been elicited, very fit and For Arduino with the build circuit prototype.

Features:
Small soldering area.
All pins are brought to the top level.
5V, GND, and Raw pins are exposed as well.
SOIC place for IC.
The mini breadboard has 170 tie points.
Prototype Size:7cm x 5.5cm x 2cm .
Mini breadboard size: 4.4 * 3.4 * 1cm .
