USB B cable connector & debug USB port

Other Parts Discussed in Thread: EK-TM4C123GXL

Hi,

I've just got the EK-TM4C123GXL Launchpad Evaluation Kit and I am starting with the out-of-the-box demo.

It should be simple, but as a brand new device it is not clear for me how to match the micro USB cable B connector with the on board USB debug port connector.

Does the "B" label on the cable go down or up?. It seems that the wider side go up, but it doesn't match easy.

Please confirm, before I make a mistake!

Note: I watched the Tiva™ C Series TM4C123x MCUs – Universal Serial Bus (USB) video expecting to get a picture of how to connect the cable, but nothing about this basic issue is shown there.

Hi Manuel,

You can refer to the "Board Overview" from the Tiva Launchpad User's Guide below.

Thank you Kel, but looking carefully to both connectors I can figure out that B label goes down.

Manuel,

I don't have a USB cable B connector here.

Usually with USB cables, the one with the USB symbol side is the top side when connecting. Most likely for a USB cable B connector, the side with the "B" symbol is the top side when connecting.

You can also do, like connecting peripherals to your CPU. Just connect wherever the connector fits.

The "B" label goes down, the "wide" side of the connector is "up". It is a tight fit, but that is the proper orientation for the connector.
