this is the next BBBmini Rev. 1.6 wish list. After discussion I will sort the requests into YES, MAYBE, NO.
I am planning to mount it directly on the cape with standard LEDs. == I will upload a picture of the montage.
you can use the PWM outputs as LEDs as well https://www.youtube.com/watch?v=GulHqnTuCfs .

I'll get both the LED & Buzzer installed on my new build. Thanks !!
Is this method being implemented within Ardupilot as a standard status LED ?
Otherwise, I will stick with Vinicius configuration on the actual build and definitively shift toward WS2812 LED support on the next builds.
P.S" No comments on the reuse of channels 7-12 as expansion connectors to free up space on deck ?
I think if space allows it would be great to add a few holes for mounting the display on top ?
Maybe place a WS2812 under it and it might look cool as well :)
Here is my ArduPlane BBBMINI Build rev 1.5 -C
- Hijacked the CanBus right legs for the Analog Airspeed and left leg for the LED & Installed these (A & C ) on a remote board with pulldown resistors and covered these with yellow heat shrink... yeah it looks like a paperbag man !!
- Deadbug installation of a FET and resistor directly on PWM number 8 connector for the Buzzer
thanks for the suggestion, but I do not want to put HF on the BBBmini. And first there must be a working driver for the rfm23bp.

what about the rfm23bp support ? we are ready to make the driver for it
you are right, most users need not more than 6 PWMs, but I will not reduce the number of channels yet.

Some additional mods
A) Lowering the modules = Changing connector type can help getting a lower profile (5mm).
Please note that these are the 4 ports unidirectionnal level shifter ( less than 1$ at ALIEXPRESS) that could be used as PWM drivers.
B) Optimization of the rear end connection
Reduce the number of PWM channels to 1- 6 and move on connector 7-12 these IO:
C) CANBUS == Please ask if ANYONE is using it
You could easily use this space for the bidirectionnal level shifter == Adafruit TXB0108
don't want to request to much without actually contributing to the PCB but is SBUS output feasible maybe?
I am voting for leaving CANBUS on the Board as i want to test it when more cheap CAN ESC's show up. Its just that no one developed a ~50€ version yet.
Regarding SMD I think i could mount a SMD WS2812 LED on to the board easy, transceiver, resistors etc would probably work as well with some practice.
Rev. 1.6 should get a new low profile case and with Display in the lid then.
