Anyway, are there Plug like cables that are better than the Breadboard Jumper Cables? The pins on the boards and even the M5 Atom are wider than a Grove cable. Is there a term for them?

Gove Cable vs other

This shows the Grove cable on the bottom. Does the top cable have a name/standard? The pins are wider. These are from the Stepper Motor and plug into the ULN2003 HDriver board (the one not labeled HDriver) (turns out the M5 HDriver couldn't power the stepper motor with enough torque. Instead we use this ULN2003 driver.)

What we want are plugs like this that can plug into the M5Atom and into other pins (basically like the HDriver from M5 - on left). So a male plug into the M5Atom and a female into the raw pins of the Driver board (Upper middle).

Finished wires

This shows a finished version with those jumper cables (and I need shorter ones). The lid with the motor goes in right on top of the blue case. (The stepper isn't plugged in yet). There is a small black buzzer (optional sound) under than blue angled piece.

We are looking for any ideas on making these connections more rock-solid like the Grove or other plug-in wires.
