The gyros and the acceleration sensors are enough for flying. And yes, previously I meant the image sensors. I want to build a flying full-sphere panoramic cam. For that we need the help of Oleg, connecting four sensor boards and combining the pictures of four sensors into one video frame. The sensors are 4x4mm each, I think Andrey can find a place for them if he is interested. > > > Whats the best place to connect the devices to the I²C bus and do > > you know which latency to expect between receiving data from the sensors > > and sending them out to the motor controllers, given no processing takes > > place? > > It might be that a dedicated processor in a feedback loop, gives better > results, for example an ardupilot interfaced to the Elphel.
