VSP driver

UART4 RX and INVERTED UART4 RX share the same signal line, so only one should be connected at a time. For non-inverted signals (e.g. iBUS, HoTT), use the standard UART4 RX port; for SBUS (inverted), use the SBUS UART4 RX port.
AP_Periph
With the clean AP_Periph firmware this module offers 16 fully functional and customizable PWM output channels.

PWM outputs 1 to 6 support DSHOT600 and BDSHOT.
