RISK unknown to Power BBG from micro-USB w/ only +5V and ground

[charles99.chao]

Hi, All
Please access the risk for me on:
1. I try to power BBG from micro-USB with only +5V and ground pins; i.e. remove D+ and D- wire, and to connect with ethernet eth0 port.

2. I would use a +5V 3A 15watt (switch mode power supply) smps to power the BBG by the micro-USB cable. Should I put a 2A fuse between to prevent to burn the BBG?

Thanks.

Hi there~

You can power the BBG with 5V and GND directly without the D+/D-. You can add the fuse for protection, thanks.
