Hi,
My osd work on flexi port in uart mode telemetry.
But I need to add external compass to improve GPS hold : Thus in change Flexi port to I2C mode to connect this external compass with I2C link trought Flexi port.
Main port is used by GPS in UART mode

Thus one connectors for I2C OR UART. I cannot connect my OSD.
What is the solution?

Thanks

Use a NAZA (DJI mode) GPS, see the wiki, it use GPS and compass together on one port.

Or move the FlexiIO (receiver) port to PPM + Telemetry

In my case I need to use the receiver in PWM mode with 7 // inputs.... Thus,
 only solution is combo naza gps compass. The wiki shows the first  (red ) version. The question is : what about compatibility with , V2, light and low cost version..now available.
Thanks

First I open the case to confirm this.
M8N ( true or not…). Compas : seem to be QMC version. Don't care due to on board ATMEGA128 wich is building protocol. There are also some unknown parts. See picture.
The B/W wire is connected to GND. Opposite : VCC.
There is a 3v3 regulator for M8N and Mag. Others parts are directly connected to VCC input : BE sure to suply with 5Vcc on main port connector. This is connect to unregulated internal VCC on revolution board.
Both LED are un-visible under the case. One is used to confirm GPS lock.

Could you confirm  with DJI, GPS protocol, the GPS satellites constellation is no more visible under GCS?
Thanks

DJI/Naza GPS does not send satellite constellation like raw Ublox GPS does, so it cannot be displayed for DJI/Naza.

Yes it is M8N and so it will (if coded correctly inside GPS) use more satellites.
