UNO Proto Shield prototype expansion board with SYB-170 mini breadboard is designed to facilitate easy prototyping with an Arduino Uno board. It provides prototyping board space to build custom circuits and is great to build custom projects with the Arduino. All IO pins of the Arduino can be tapped into through header pins and empty solder pads for easy expansion. 5V and Gnd power rails are also available on the board. The board also has 4 general purpose LEDs and 2 general purpose switches which can be connected to any IO pin on the Arduino.

It’s got extra connections for all of the Arduino I/O pins, and it’s got space to mount through-hole and surface mount integrated circuits. It’s a convenient way to make your custom circuit and Arduino into a single module.

Features :

It has a nice standard 0.1″x0.1″ prototyping grid with big pads
Comes with Stacking headers and plain header, choose whichever you want when soldering together
An IC pattern for adding DIP ICs up to 20 pins
Power rails down the middle and sides
A reset button and an extra general use button
Two 3mm general use LEDs, red and green, as well as 2 matching resistors
A pass-thru ICSP stacking header so you can stack any kind of shield on top, and/or use an AVR programmer
A surface-mount chip area for up to 14 SOIC size parts
Compatible with tiny breadboards
GND and 5V power rails for easy expansion
4 x General Purpose LEDs
2 x General Purpose Switches
Board comes with clear and legible pin labels for rapid prototyping
Gold plated pads
2 x 0.1uF capacitors on either side for extra power stability
