Wire gauges

Sun Jan 14, 2018 7:57 am

Hi.

I’m starting to gather bits for my next rover build, going bigger this time.

Plan is to have 4x12 volt gear motors. I’ve got a nice new 11.1v lipo that is going to power the motors and a Servo board which is used for pan/tilt setup for camera. Pi will be powered separately.

The lipo has larger gauge wire, and the motor controller board (have on hand L298n and L9110 I could use). So my question is, what’s the best way to feed the heavy gauge wire into the slots on the motor controller? I’ll have the same problem with the Servo board, feeding the wire into a buck to drop down to 5v.

Many thanks.

Using "pcb screw terminals" if you can.

Or solder a molex/socket clip connector or spade connectors on with as thick a wire as you can get through for a short distance.
It also gives you an easy way to remove the battery etc.
You can buy single pins you can solder to the board and then solder directly to them too.

Thanks. The motor controller and Servo board both have the screw down terminals, so I’ll try go with something like you suggested. I have bought a few spare XT60 cables/connection so I can try a few different ways before I play with the battery.
