Soldering in the screw terminals

Solder the Arduino Headers

To interface the shield with your Arduino, soldering male connectors to the 
28 header pins is a must. Soldering ensures a reliable physical and 
electrical connection. If you’ve never soldered before, check out our 
through-hole soldering tutorial.

There are usually two options for connectors when you’re assembling a 
shield: stackable or straight. We recommend stackable headers because 
they allow you to stack other shields or jumper wires on top. The smaller 
male headers are a good option if you’re looking for lower-profile 
installation.

If this is your first shield assembly, we recommend reading through our 
shield assembly guide. There are all sorts of tricks to installing shield 
headers, and making them look as good and straight as possible!

There are too many holes!

The stackable header kit includes two 

6-position, and two 8-position headers. These go in the rows of pins 
toward the outside edge of the board. Also, both 6-positions go on the 
same side, and the 8-positions go on the other. There will be two extra 
unused pins on each side, toward the motor connection.

In the process of soldering stackable headers. Still a lot of pins to go!

Once you’re done soldering the headers, plug the shield in to make sure 
everything fits nice and cozy.
