Although I've had great success with the 'F411 based Noxe V1, this particular AIO has things allocated in a way that makes it unlikely to support any external I2C devices. And that takes out my BARO and MAG. I can free up a UART by connecting the GPS to UART2, and perhaps that will provide crude RTH, but what I'd really like of course is for HappyModel or someone to make one of these much more INAV friendly.

Any idea if the 2.4GHz version is any better in that regards ?

I'll let you know when I receive it. It looks like the VTX SA pad can be jumped to LED_STRIP instead of TX2, opening up two full UARTs for serial RX and GPS. I haven't looked at available I2C pins yet.
