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!


NOTE: Before you start: If you have a multimeter check for shorts between the GND pin hole and the other pin holes - if you find any please send us an email at support at digistump dot com and we will replace the board.

Check the contents of your kit and ensure you have all of the parts listed.


Insert the 4.7K and 10K resistors into the spots labeled for them. Solder the leads on the bottom of the board and clip off any excess.


Insert the 3.3v regulator, matching it with the outline on the board. Solder the leads on the bottom of the board and clip off any excess.


Insert the 10uf Capacitor - ensuring the lead on the side of the capacitor that is labeled with a grey stripe and minus signs is going into the hole that DOES NOT have the plus sign next to it. Solder the leads on the bottom of the board and clip off any excess.


Insert the 0.1uf capacitor as shown (lead orientation doesn't matter). Solder the leads on the bottom of the board and clip off any excess.


Insert the WiFi module as shown - into the bottom of the PCB (NOT THE TOP!) - solder the leads on the top 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.

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.
