@TomP We are still shooting for the end of this year. I would like to know what external peripherals you would like to support though. I'm guessing GPS, magnetometer, RC, a PWM based motor ESC, and some servos for flight surface control? Also an airspeed sensor? A distance sensor? What kind of RC are you expecting to use? There are some I/O limitations with VOXL 2 so want to make sure that what you want to build can be supported by what we are putting together.
