Troubleshooting - How to Use Nano HD Camera via Transmitter

Nano HD camera is the Lightest HD camera in the current market. Special customized for Beta65X HD.

How to control its video function via transmitter? Please follow the below method.

Note: There are different commands for different FC, the following method is applied to F4 1-2S AIO Brushless Flight Controller (No RX) and  F4 1-2S AIO Brushless Flight Controller(Build-in RX).  If your FC is others or your transmitter cannot operate it even though you follow the below method, please check this article to troubleshoot.

As usual, we use the 5V, GND, and CAM pads for most of the functions. For options,  if you want to change the configuration of the camera, there are some modifications needed. Remove the 6-pins black connector and use the ADC pad.

How to control its video function via transmitter

What is the function of the ADC pad? You could control the FPV camera via your radio transmitter, like change the configuration of the camera OSD menu, start/stop the recording etc.

You need to configure your FC before you could use this function. 

• Use the connection diagram with F4 1-2S AIO Brushless Flight Controller(Build-in RX) for example. First, check the connection diagram below, the ADC pad is connected with the LED pad on the FC board. So you need to enter the CLI commands via the Betaflight Configuration.

Command

resource LED_STRIP 1 NONE
resource CAMERA_CONTROL 1 A00
set camera_control_mode = HARDWARE_PWM
set camera_control_ref_voltage = 330
set camera_control_key_delay = 200
set camera_control_internal_resistance = 99
set camera_control_button_resistance = 125,110,90,75,20
set camera_control_inverted = OFF

• Use the connection diagram with F4 1-2S AIO Brushless Flight Controller (No RX) for example. First, check the connection diagram below, the ADC pad is connected with the LED pad on the FC board. So you need to enter the CLI commands via the Betaflight Configuration.

Command

resource LED_STRIP 1 NONE
resource CAMERA_CONTROL 1 A08
set camera_control_mode = HARDWARE_PWM
set camera_control_ref_voltage = 330
set camera_control_key_delay = 200
set camera_control_internal_resistance = 99
set camera_control_button_resistance = 125,110,90,75,20
set camera_control_inverted = OFF

 

Note: If you use another pad on the FC board for this function, you should change the port in the CLI.

If the configuration works correctly, you could enter the Nano HD camera OSD with the Joystick gesture below.
