F3FC board help

[Richard]

Hi Everyone,

Finished building my Mini Tri last night and started the cleanflight setup.

Everything was going smoothly until I plugged the battery in, to setup the receiver. Now the board is unresponsive when plugged into cleanflight, and only one esc tone sounds when the battery is plugged in. I have pulled it down to check for bridged solder connections, all connections seem to be correct.

Any suggestions? What now I guess?

you could start by reflashing just in case. when unplugged push the little push button on the side of the board, plug usb while keeping the button pushed than flash via the cleanflight interface.
David’s youtube channel also shows how to do this:

I tired this but nothing happens.

Start with the basics – are any leds on, do you have 5v where you expect it to be, do you have 3.3v where you expect, what current is the board drawing from the battery, what USB descriptors is it presenting to your pc, are there any solder splats or little bits of wire around the place, start disconnecting things like ESCs, receivers etc.
