-The Little Wire on Digispark Shield Kit connects ​provides a Little Wire compatible pinout on the Digispark. This allows the Digispark to be easily used as a Little Wire device, with the Little Wire firmware and libraries. The shield also provide pull-ups for the I2C lines, which can be enabled by an included jumper, and an external power jumper. The kit also includes a 6 pin IDC cable for connecting to other circuits or to standard 6-pin AVR ISP headers for programming AVR chips.+The Little Wire on Digispark Shield Kit provides a Little Wire compatible pinout on the Digispark.

-Little Wire is multi-featured USB controlled Open Source Hardware tool packed in a minimal form factor designed by Ihsan Kehribar. Little Wire appears as usbtinyisp device and provides a tethered interface between hardware and a computer.+Little Wire is multi-featured USB controlled Open Source Hardware tool packed in a minimal form factor designed by Ihsan Kehribar. ​The Little Wire for Digispark shield was designed by Ihsan in collaboration with Digistump. The Little Wire firmware can be easily loaded on to Digispark for use with the Little Wire for Digispark shield.

-If using the cable - plug into 6 pin header.+Cut a length of male headers 6 pins long and one 3 pins long. Insert into corresponding positions (on the bottom of the board) and solder each pin. 
 + 
 +**Tip:** Inseting the headers into a breadboard and then placing the board on top can make this process easier. 
 + 
 +**Note:​** ​If you are using stackable headers, use them here instead of the standard male headers.

 Run the executable and when prompted plug in the Digispark that you will be using with the shield. When complete the Digispark will now appear as a Little Wire device 5 seconds after it is plugged into the computer. ​ Run the executable and when prompted plug in the Digispark that you will be using with the shield.
