I’m currently building a robot arm using four DS3240 motors and an SMPS 350-5, connected to an Arduino Uno and my laptop. When connecting the SMPS to the motors, what kind of wires should I use? The wire thicknesses are different, so I can’t connect them directly.

Operating Voltage: 4.8V ~ 6.8V (i got smps 5V)

Rotation angle:180 degree

Stall Current: approx. 2.5A ~ 3A(i got 4 motors)

Can you give me advice?
