-======Pro BLE/BT 4.0 Shield Kit Tutorial======
-=====Product Description:=====
-[[https://s3.amazonaws.com/digispark/images/m/ble1.jpg|{{https://s3.amazonaws.com/digispark/images/t/ble1.jpg}}]]
-[[https://s3.amazonaws.com/digispark/images/m/ble4.jpg|{{https://s3.amazonaws.com/digispark/images/t/ble4.jpg}}]]
-This is an unassembled kit and requires basic soldering. This is designed for use with the Digispark development board, which is not included.
-=====Parts:=====
-^ Part       ^ Quantity          ^Identification^
-| Bluetooth/BLE Combo Shield PCB|1| |
-| 6 pin 0.1" Right Angle Female Socket |1||
-| HM-10 BLE Breakout Module |1|
-| 1x40pin male 0.1" pitch header| 21 pins worth| |
-**Resistor Values:** For more information on how to identify the value of the resistors we recommend these sites:
-A nice simple resistor calculator: http://www.ealnet.com/m-eal/resistor/resistor.htm
-A comprehensive article on identification: http://www.diyaudioandvideo.com/Electronics/Color/
-**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, acquire parts) and verify contents.
-[[https://s3.amazonaws.com/digispark/images/m/ble1.jpg|{{https://s3.amazonaws.com/digispark/images/t/ble1.jpg}}]]
-Insert 6 pin right angle socket into top of PCB - insert it into the set of 6 holes that say "BLE BT4" below them - this is the second set from the right edge of the board. Solder socket pins on the bottom of the board
-[[https://s3.amazonaws.com/digispark/images/m/ble2.jpg|{{https://s3.amazonaws.com/digispark/images/t/ble2.jpg}}]]
-Cut two lengths of male headers each 9 pins long and one 3 pins long. Insert into corresponding positions (on the bottom of the board) and solder each pin on the top.
-**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.
-[[https://s3.amazonaws.com/digispark/images/m/ble3.jpg|{{https://s3.amazonaws.com/digispark/images/t/ble3.jpg}}]]
-Insert the HM-10 BLE breakout module into the 6 pin socket as shown.
