Hi Bitcraze team !
Everything is in the title.
I may have missed something but I can't find any information about this.

Hi Jeremix,
The radio module we use for loco positioning, the dwm1000, is consuming about 200mA on 3.3v when in transmit or receive mode. So this is the high estimate of the power consumption. The reason why it is not specified yet is that the actual power consumption will depend a lot of the use case. For example with the new TDMA code the Crazyflie does not use that much anymore since it does not communicate all the time.

Thank you Arnaud.
I was wondering about the battery solution for powering the anchors.
Mine are 6000mAh. So it's about 30 hours of power...
It should be ok !

I have been testing that I can run with a 2200mAh for about 6h without problems, after that it is still working but the anchor resets every now and then (witch gives some very interesting fly-away and come back flight pattern
). So more realistically you should get at least 16h (could be more, depending on how accurate your USB battery capacity is specified).
