Arduino Uno Proto Shield gives possibility to carry your Arduino projects from breadboard and turn them into a proper circuit and also use your specially designed circuits with Arduino.
You can use prototype shield without soldering.
Breadboard you placed on middle section you can do prototyping and tests without dealing with soldering.prototype Shield provides easy usage by carrying all Arduino pins to upper layer. Also there places on prototype shield for surface mount devices (SMD). Therefore you can use that type of materials as well.
Arduino Uno Proto Shield has R3 pin sequence and there is a reset button on board. All headers and connectors are sent soldered.
