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

Post by charles99.chao » Wed Sep 04, 2019 3:32 pm

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.

Hi bill,
Thanks for the help but other issue comes up!!
I got the power set up and my BBG can boot (LEDs lite up ok) but I can not connect/access to BBG with ethernet cable !

I try to set static IP adress http://derekmolloy.ie/set-ip-address-to ... one-black/ for BBG but with no luck.

Is there any advise for this setup or better to switch to a BBB where a power plug is ready made!

My application is a FA project; eventually I need the BBG to be standalone without PC/NB.
