Re: CrazyFlie 2.0 - Propellers won't turn, won't turn on unless plugged in

So I think I've identified a potential problem. It appears that the battery connector has been soldered to the board with the polarity reversed. I could at least attempt to de/re-solder the connection appropriately if you think that is potentially the root cause. Otherwise some kind of RMA or replac...

I've received the new battery today, and charged it for over an hour. I'm still seeing the exact same behavior as in the original post. Will not turn on unless plugged in to USB.

Do you have access to a multimeter you could check its voltage with just to be sure? I checked the following: When plugged in: VUSB +/- = 5.12V VCC/GND = ~3V When not plugged in: VUSB +/- = 0V VCC/GND = 0V It still does not power on when plugged in. I'll go ahead and send an email to support.

Assuming that doesn't work, what are the next steps? UPDATE: I've had it charging for about 2 hours now. Absolutely no response...

CrazyFlie 2.0 - Propellers won't turn, won't turn on unless plugged in

Just received my CrazyFlie 2.0 today. I followed the assembly instructions, board passed self-test etc... However now that the drone is fully assembled I'm noticing a couple behaviors: When plugged in to the USB, the blue LEDS are solid lit, and the red LED blinks twice per second, indicating all is...
