These are random AP-related notes that wouldn't fit anywhere else:

## DMA on the Matek F405-Wing
|
|
|
|
If you want to get DMA on UART3 of the Matek F405-Wing FC (or, more relatedly, the Racerstar F405, because UART1 is Bluetooth there), you can open `libraries/AP_HAL_ChibiOS/hwdef/MatekF405-Wing/hwdef.dat` and comment out line 92ish, where PA15 is defined.
|
|
|
|
That will enable DMA on UART3, at the expense of disabling the LED pad.
