hillz Posted February 26, 2017 Share Posted February 26, 2017 Yesterday I nearly burned my orange pi zero because of the faulty LAN cable, after that, everything I plugged into the expansion board couldn't be detected anymore by lsusb or dmesg, it works fine though if I plug in my thumb drive / usb wifi into the usb port on the main board (Next to the LAN port). How do I know for sure that my expansion board is broken and not the pin headers in the main board ? I'm not an electronic guy I don't know anything about soldering and stuff.

awef Posted February 26, 2017 Share Posted February 26, 2017 mostly everything on the expansion board is "brainless", so if it doesn't work, it's probably your main board Link to comment Share on other sites More sharing options...

awef Posted February 26, 2017 Share Posted February 26, 2017 Probably the case. The expansion connector 95% just converts pins into pretty shaped connectors that you're familiar with. Link to comment Share on other sites More sharing options...
