Following is the thread that I've posted in RCGroups https://www.rcgroups.com/forums/showthread.php?2912273-Matek-Flight-Controller-F405-AIO/page7#post37981481.

As asked, now filing an issue as a reminder.

I've downloaded and installed the iNav inav_1.7.3_MATEKF405_483a42a3.hex and installed onto my MATEK F405-OSD AIO board. It managed to recognize all my devices and seemed working fine ( gyro, acc, gps, baro, mag all responded to movements ).

The only thing that doesn't work, is the led. I connected led stripe to the led out pad, then enabled led stripe in 'configuration', then it started to beep rapidly. I assume that means some error.

So I researched and found your post here saying "I2C requires that the WS2812 led strip is moved to pad S5 / pin PA15 (motor 5), thus WS2812 is probably only usable on quadcopters.". So I just simply moved my led stripe's DIN wire to S5 pad, but it won't work ( all lights out ).

So does that mean I need to solder the led stripe's signal pin ( the DIN ) to S5?
And do I need to remap the LED resource to S5 and how can I do that in CLI?

Following is my current resource map. Hope I can eventually get my led to work. Thanks a lot!
