CH 7 (RX) from UART1 TX
CH8 (TX) to UART1 RX,
+5V, GND
CROSSFIRE DIVERSITY to COLIBRI FC cable, plugs
into UART1 port on FC:
• Servo header #1 on CH 7 (signal pin only):
- Pin 1 - Crossfire output 7 RX from FC UART1 TX
• Servo header #2 on CH 8:
- Pin 1 - Crossfire output 8 TX to FC UART1 RX
- Pin 2 - Servo rail to FC +5V
- Pin 3 - Servo header GND to FC GND
CROSSFIRE DIVERSITY TX configuration:
Under receiver settings, map output 7 to “CRSF
RX” and output 8 to “CRSF TX”.
The bi-directional serial communication carries
R/C control signal, no need for R/C IN connection.

will get +5V and
GND from BST line
(also supplying servo
connectors).
Note: The TBS PDB will
not power the BST line,
only FPVision.
FPVision alt.:
If you use the FPVision
layer, you can decide
if you want to use UART2
on the FPVision (which is
routed to COLIBRI FC
through the stacking
header).
