Hi everybody ! This is my first post on this forum.
I work as an hardware engineer in consumer Drone industry.
During development phase, we often have to record several analogue signals during flights. The logger hardware has to be the smallest/lightest available, since we want to limit the impact of the recorder on motors throttle and aerodynamics. Teensy boards are incredibly small, so it seems perfect for the job ! I already bought a couple of Teensy 3.2 and SD adapters (the small ones).
What I want to achieve :
If wav is a problem I can deal with recording raw data and encapsulate later, but I suppose SD latency is the real hard bit.
Since I am not familiar with these boards, I don't know if my project is feasable. I wouldn't like to waste my time on an insuitable solution.
Thanks
Clovis

What I want to achieve :
- size of an USB key
- less than 17 grams
- stereo 16-bit PCM WAV,@ 44100Hz
- USB-MSD when plugged to a PC, to copy WAV files
