Cosmostreamer DIYDJI Mavic Mini/Mini2

Hardware

Only Raspberry Pi 4B may be used for USB connection to DJI Mavic Mini/Mini2

Raspberry Pi 4B
  • Two micro-HDMI outs
  • Analog video out (CVBS, TV-out) in 3.5 mini-jack
  • Wi-Fi 2.4/5 GHz
  • Ethernet 10/100/1000 Mbit/s
  • 2 USB 2.0 ports + 2 USB 3.0 ports
  • 1 USB-C port
  • Telemetry OSD on HDMI over video is NOT available.

It's good for clean video HDMI output, for local/internet streaming, for controlling DJI Mavic Mini/Mini2 camera from USB joysticks/gamepads or from keyboard/mouse in client application.
It's not good for DJI Mavic Mini/Mini2 remote control for operator with HDMI monitoring, because HDMI shows only clean video, no recording state, no image values.
