Build your own Arduino shield using the compact and flexible Proto Shield kit. Solder together a limitless range of circuits and reuse it in all your Arduino projects. A standard 0.1" prototyping grid accepts commonly used through-hole parts and chips. You could also find a range of basic components are included to help you get started with your custom shield.
Features:
Standard Arduino compatible
Large 0.1"*0.1" pitch prototyping area
A variety of through-hole sizes to fit most parts
Arduino UART and I2C port pin breakout for easy external communications
Dual ISP breakouts for easy programming and stacking
3.3 volt, 5 volt, and ground power rails are easily available anywhere on the board
Breadboard style prototyping area
USB type B breakout
Basic components included (buttons, switches, LEDs, resistors, USB jack)
