New MMM field programming cards

[BrianG]

The USB is only used when you want to use the computer. Period. When the card is hooked up to a computer and an ESC, it ONLY functions as a Castle Link device.

In your case, you will want to plug the ESC throttle cable into the card, hook up your battery to the ESC, and you will also need a way to power the card itself with 5-6v. This is why I said to temporarily put the red wire into the ESC throttle cable.
