Wiring / Switching
- Switch camera through servo mapped to LED.
- Switch camera through servo mapped to motor 5.
- The flight controller is connected to the CAM2 port by default. Switch to the CAM1 port using the USER1 soft serial. In Betaflight Configurator, enable USER1 in the modes tab and map it to the corresponding switch to toggle between camera feeds.

Details

The Axisflying NAJA dual optical module combines two front-facing lenses in one compact housing for FPV DIY builds.

The ECO NAJA dual optical module combines a NAJA camera and a thermal camera in one stacked unit weighing 70.4g.

The dual-lens module measures about 50.02 mm long, 33.07 mm tall, and 14.04 mm wide for easier mounting planning.

The NAJA dual camera module can be wired to CAM1/CAM2 with 5V and GND, and camera switching can be mapped via LED or motor 5 in Betaflight.

NAJA camera specs list 1500TVL CVBS output with 125° FOV and DC 5V–28V input, alongside TC256/TC384/TC640 thermal options with CVBS output and 5V–16V power input.
