Hi all,
I recently bought a DJI f550 kit as my first proper multirotor (I've also got a Blade mQX). I matched it with a Multiwii PRO 2.0 from witespy (with straight pins installed and a uBlox 6M GPS chip). I built it all and had a fairly successful maiden flight, then realised that I needed to enable the gyros in the Multiwii GUI (I figured they would be enabled full-time, automatically). When I went to plug the micro USB cable in, the socket snapped off the Multiwii board.
I spent a few days researching USB sockets and figured that I'd replace the broken micro USB socket with a mini USB socket, readily available from an electronics store near me. I chose to go mini USB over micro USB as I couldn't find a source for micro USB sockets in Perth, or even Australia for that matter. The pinouts for micro and mini USB are almost identical, as shown in the links here for micro USB and mini USB.
After I had purchased the mini USB socket, I put it onto the end of a mini USB cable, plugged the other end into my computer, and held the socket on the Multiwii board in the position where it would be soldered. The board lit up and booted as normal.
Yesterday, I had the mini USB socket soldered on by a professional, as my soldering skills definitely do not cover small surface mount devices.
Now, I got the board back today. With nothing connected, I plug the board into my computer using the same USB cable as yesterday. The board shows one blue LED and doesn't communicate with my computer at all. The same thing happens when I wired everything up and plugged in my lipo (with my ESC's beeping as if they aren't plugged into the Multiwii at all).
The only reference I can find online to a Multiwii PRO 2.0 board showing a blue LED is here. A supplier trying to sell a customer's returned Multiwii board suspecting that it's bricked.
Any help or advice for my situation would be greatly appreciated! Sorry this post was so long, ahah.
Thanks,
Sam
