Crazyflie 2.0 Not Working Out of the Box

Post by antgiant »

Out of the box my Crazyflie 2.0 is not working. This video shows the light sequence for the self test and then when attempting to connect over USB.

Things I have tried.
Connecting to provided VM. Always insta-reboots and no longer is visible to the computer.
Tried connecting via iOS device and Android device (via bluetooth). In both cases appears to be successful but cannot control or receive any data.
Tried updating firmware. Appeared to be successful twice (via iOS) no change in behavior. Device is invisible to VM and Host over USB when in bootloader mode.

Hi!

I'm thinking there can be two causes.
1. The power from USB is not enough and it reboots because of that.
2. One of the mosfets / connectors have shorten and which is causing the reboot.

Can you please inspect the soldering of motor connectors on the PCB. Look for any possible short. If so the easiest is if you can fix the soldering your self, else we will send out a replacement board (or if the soldering fix doesn't work). Then send me your shipping details in a PM.
