-======Boost Shield Kit Tutorial====== 
  
-=====Product Description:​===== 
-[[https://​s3.amazonaws.com/​digispark/​images/​m/​boost9.jpg|{{https://​s3.amazonaws.com/​digispark/​images/​t/​boost9.jpg}}]][[https://​s3.amazonaws.com/​digispark/​images/​m/​boost2.jpg|{{https://​s3.amazonaws.com/​digispark/​images/​t/​boost2.jpg}}]][[https://​s3.amazonaws.com/​digispark/​images/​m/​boost1.jpg|{{https://​s3.amazonaws.com/​digispark/​images/​t/​boost1.jpg}}]] 
- 
-The Boost Shield Kit allows you to use supply voltages under 5v with the Digispark development board. The Boost Shield boosts a 2-4.5v supply (including 2 aa or aaa batteries, or on lipoly) to 5v and connects directly to the Digispark. 
- 
-This is an unassembled kit and requires basic soldering. This is designed for use with the Digispark development board, which is not included. 
- 
-This kit is based on the MintyBoost design by Adafruit!

-**Soldering:​** If you are new to soldering we recommend the following tutorials: 
-Soldering Basics (http://​www.sparkfun.com/​tutorials/​106) and Soldering Crash Course from the folks at Sparkfun (http://​www.sparkfun.com/​tutorials/​354). 
-How to solder from the Curious Inventor: http://​store.curiousinventor.com/​guides/​How_to_Solder 
- 
-Adafruit has this excellent guide that starts with the tools needed and then shows detailed pictures, including some of the common problems that beginners experience (http://​learn.adafruit.com/​adafruit-guide-excellent-soldering) 
- 
-**We assume for these assembly instructions that you know the basics of thru-hole soldering. If you don't check out the links above, these boards are very easy to solder - we promise!** 
- 
- 
-=====Assembly:​===== 
- 
- 
-Empty kit bag (or if using a raw PCB, aquire parts) and verify contents. ​ 
-**Note for Kickstarter Backers and Pre-orders:​** Headers are not included in each kit bag, but the entire order came with more than enough headers for all kits.

- 
-Insert the diode ensuring the directional strip on the diode is on the same side as the printed stripe on the board. Solder the leads and clip off the excess.

- 
-Insert the two 0.1uf capacitors. Solder the leads and clip off the excess.

- 
-Insert the 8 pin DIP socket into the board matching the indention cut out on one end with the indention printed on the board. 
- 
-Insert the two 220uf capacitors, ensure that the longer lead is inserted into the hole with the + sign next to it. Solder the leads and clip off the excess.

- 
-Insert the inductor. Solder the leads and clip off the excess. 
- 
-[[https://​s3.amazonaws.com/​digispark/​images/​m/​boost5.jpg|{{https://​s3.amazonaws.com/​digispark/​images/​t/​boost5.jpg}}]] 
- 
-Insert the 2-pin screw terminal with the hookup openings facing outward. Solder the two pins. 
-

- 
-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:** Inserting 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.

- 
-Insert the LT1302-5 IC into the 8 pin DIP socket matching the indention cut out on one end with the indention on the socket.

- 
-=====Usage:​===== 
- 
-Connect the + and Gnd (or -) from a power source of 2-4.5V (likely a battery) to the corresponding inputs on the screw terminal. 5V will be provided to the connected Digispark.
