Resistor Values: For more information on how to identify the value of the resistors we recommend these sites: A nice simple resistor calculator: A comprehensive article on identification:

Soldering: If you are new to soldering we recommend the following tutorials: Soldering Basics ( and Soldering Crash Course from the folks at Sparkfun ( How to solder from the Curious Inventor:

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 (

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!


Empty kit bag (or if using a raw PCB, acquire parts) and verify contents.


Insert 6 pin right angle socket into top of PCB - insert it into the set of 6 holes that say “BLE” next to them - this is the second set from the bottom edge of the board where one row shows “BLE” and the other “BT”. Solder socket pins on the bottom of the board.


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.

WARNING! Ensure you do not solder one of the 9 pin set of male headers on the row with the arrows pointing to the row described as “PRO SHIELD USE ONLY”. You will need to solder it into the row of holes in the middle of the board with “GND” on one end and “EN” on the other.

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 AC-BT-V4 BLE breakout module into the 6 pin socket as shown.


Your Oak Bluetooth Low Energy shield is complete!
