Prepare the header strip:
Cut the strip to length if necessary. It will be easier to solder if you insert it into a breadboard - long pins down
Be sure to solder all pins for reliable electrical contact.
(For tips on soldering, be sure to check out our Guide to Excellent Soldering).
Next we will solder in the two 3.5mm terminal blocks used to connect power & the motor to the breakout board.
Make sure the open parts of the terminals face outwards so you can easily connect wires
To make it easier to keep these in place, you can use some tape to hold down the two header pieces. Tacky clay also works, whatever you've got handy!
