It has a nice standard 0.1″x0.1″ prototying grid with big pads
A 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
2 3mm general use LEDs, red and green, as well as 2 matching resistors
The ICSP header is up top if you like to upload to your Arduino using a programmer
A surface-mount chip area for up to 14 SOIC size parts
Compatible with either tiny breadboards or ‘standard’ breadboards with the rails removed.
Every pin is brought out, including the new 3V and Reset header pins
2 0.1uF capacitors on either side for extra power stability
The shield brings all Uno I/O up to the top of the board and provides a remote reset button. There is also a general purpose pushbutton which provides a ground contact when pressed as well as 2 general purpose LEDs with resistors which are active high.
There is an SOIC-14 solder footprint which is brought out to two header locations. The shield also has a spot to add an ICSP header if desired.
The prototyping board has both GND and 5V solder type buses as well as 2 female header buses that are also connected to GND and 5V. There are 2 locations provided on the board to add bypass capacitors across the 5V / GND rails if desired.
It works with UNO, NG, Diecimila and Duemilanove Arduinos. You can use it with a Leonardo but it will not break out the hardware SPI pins (they’re only on the ISP connector underneath) or the IOREF/SDA/SCL pins. However, the SDA/SCL pins on the Leonardo are also on digital #2 and #3 so you can still use them by connecting to #2 and #3.
Uno Proto Shield and SYB-170 Breadboard
Provides prototyping area that mounts to the Uno and compatibles as a shield.
The Uno Proto Shield and SYB-170 Breadboard mounts on top of an Arduino Uno or compatibles with the same header pinout and provides both a solder type prototyping surface as well as an SYB-170 solderless breadboard that can be temporarily or permanently mounted to the shield.
PACKAGE INCLUDES:
Uno Proto Shield
SYB-170 Breadboard that can be adhered to the top of the shield or not depending on planned use
