SERVO13_FUNCTION 120, NTF_LED_TYPES neopixel
PWM1~PWM13 are Dshot and PWM capable. However,  mixing Dshot and normal PWM operation for outputs  is  restricted into groups, ie. enabling Dshot for an output in    a group requires that ALL outputs in that group be configured and used as Dshot, rather than PWM outputs.

If servo and motor are mixed in same group, make sure this group run lowest PWM frequency according to the servo specification. ie. Servo supports Max. 50Hz, ESC

must run at 50Hz in this group.
