Hi team,

I have seen other threads on the same issue ...
my brand new crazyflie 2.0 from seeedstudio has i2c error 1024 with lps25H sensor.

I have contacted their support but no answer for now... can you help me to get a new cpu board ?

(btw, it flights with custom firmware and sensor disabled, but this is for edu. and I need fully functional copter)

regards
raph

Moved to Crazyflie Nano Quadcopter->Support since it's more applicable and might get better visibility.
