Using Caddx Micro SDR1 Camera with Betaflight Camera Control

The new Caddx cameras seem interesting, so I got a Micro SDR1 for myself to try out. Not so surprised, I ran into problems with Betaflight Camera Control.

The flight controller was a Matek F411-MINI which has a ready-to-use camera control pin(no need resistor and/or capacitor).  The OSD pin of the camera was directly soldered to the RSSI pin of the FC board and the resource remapping command was correctly set and saved according to Matek’s manual. But the Betaflight Camera Control didn’t work.

Thanks to jumatic on github:

Put a 330 om resistor between the RSSI pin and the Camera, then with below settings it works perfectly.

camera_control_mode = HARDWARE_PWM
Allowed values: HARDWARE_PWM, SOFTWARE_PWM, DAC

camera_control_ref_voltage = 317
Allowed range: 200 - 400
Default value: 330

camera_control_key_delay = 120
Allowed range: 100 - 500
Default value: 180

camera_control_internal_resistance = 264
Allowed range: 10 - 1000
Default value: 470

camera_control_inverted = OFF
Allowed values: OFF, ON
