How to Solder a U3V70F12 Motor Driver Carrier

This method works for any of the U3V70x series voltage regulators found on www.Pololu.com

Personally with the amount of current capacity I would always vote for using the wire clamps over the pins. Most breadboards can only handle 1-2A of current safely.

WARNING: Do not solder the pins on if you plan to use the wire clamps, you will be exposing voltage through the pins that could easily short on an object including yourself.

How to Solder Motor Wires

How to Solder Motor Wires… so they last

Steps:

  1. Cut wires for the length you require, I usually cut a little longer because you can always go shorter.
  2. Strip wires (about 1/2″)
  3. Tin wires, apply solder to the bare wire ends
  4. Solder wires to the motors using either a J hook method or just straight through (I would go straight so they’re easier to replace)
  5. Cover with heat shrink tubing. Go with the first size that fits over your wire, if that isn’t big enough to go over the connection as well then apply the first size to your wires, then encase the connection and the first layer of heat shrink with the next biggest size.
