mocart with this support probably I will migrate to pixhawk connected fully to RPI with telemetry in one time.
mocart I need to start to think how to power RPI3, right now camera and android PC are conected to small power bank with 2 out ports (2A&1A ) and this work fine. I`m afraid RPI3 will require more power than Android or RPI2.
Im using a 5v, 5A bec to supply my RPI, that includes RPI, Pixhawk, camera, 4G Dongle..
I think max current is about 3A at most, but im not sure.
One thing that is really important is to share ground if you power Pixhawk and RPI from two diffrent power source. Serial communication needs common ground to work properly.
If you power all devices from one source, this wont be an issue
