Low price equals low quality. At least usually. I became clear to me (again) when I’ve broken USB port on my Flip32+ multirotor flight controller. I’ve pulled USB cable and USB socket stayed on a plug. Cheap solder. Or too quick soldering. No idea. Bottom line: unable to connect to flight controller board using USB cable. To make things worse, quadcopter was not tuned yet. It was flying, but not in the way I wanted it to.
What are the options in this case? Well, there are 3:
- get new flight controller board. Quite expensive since the only thing that is broken is USB port itself. Everything else works just fine,
- resolder USB socket. Might be the best solution, but since it’s surface mounted micro USB, it’s way above my soldering skills. THT? Why no prob. Simple SMD like resistor? Why not. More advanced? No…,
- use different way to communicate with flight controller.
I’ve chosen the third way. Flip32 (and Naze32) has build in hardware UART ports (as well as SoftwareSerial) that can be used to establish connection with a PC. Software like Cleanflight already allows you to use any serial port to talk to flight controller. Continue reading “Flip32 with broken USB port” »
