Hi all. Among the two F745 autopilots that ArduCopter is now supporting, the Kakute F7 is seeing extensive use while the Omnibus F7 is apparently less well used or documented. I am planning a build with the latter, so here I’d appreciate if somebody could sanity check my setup / wiring.
By reading the hwdef I have worked out the wiring as follows:
USART1 -> Telemetry Radio
USART2 -> SBus (If a PPM signal is connected to the SBus pin, does the autopilot auto-detect PPM?)
USART3 -> Pins used by I2C for external compass
USART6 -> GPS
USART7 -> BlHeli32 telemetryA crude diagram is prepared too. Don’t hesitate to point out errors, I’ll correct any immediately.
Some additional questions
- Is there a reason in hardware or performance why the OmnibusF7 is scarcely used?
- Is it possible to use the external baro in the HERE 2 GNSS and bypass the internal baro on Omnibus / Kakute boards?
- One of my reasons to NOT use the kakute is that I need PPM input for RFD900X RC passthrough. Does anyone see a problem with that?
