Hardware

Cosmostreamer for DJI Go4 drones can work on these boards:

Raspberry Pi 4B

Any RAM size. 1Gb, 2Gb, 4Gb, 8Gb.

• Two micro-HDMI outs, both can be used for video output
• Analog video out (CVBS, TV-out) in 3.5 mini-jack
• DSI display may be used. If DSI display connected - video output available only on this display + HDMI-0 port.
• 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 (used for drone controller connection)

Installing the Cosmostreamer firmware

1. Get a blank microSD card of 8GB or larger. Insert the microSD card into the card reader
2. Download ZIP-archive with firmware content
3. Extract .img file from downloaded ZIP archive
4. Use Win32DiskImager on Windows or Balena Etcher on Mac and write .img file on microSD card
5. Insert the microSD card into the Raspberry Pi
6. If you have a monitor or a TV with HDMI input - plug it to the Raspberry Pi 4B HDMI-0 port (nearest to USB-C port)
7. Plug a standard USB power supply or powerbank to the Raspberry Pi (go to chapter Power for Raspberry Pi). Raspberry Pi must start booting. A couple of reboots may be during the first boot process.

Power for Raspberry Pi

For using with DJI Go4 drones controllers Raspberry Pi 4 must be powered ONLY from GPIO or from PoE or via USB-C port with custom cable.

Power with GPIO (pins)

Use any USB cable, need to cut it and connect to the RPI only 2 wires - Red (5V) and Black (Gnd). Then you can use it with any standard USB power supply or powerbank.

Power with USB-C port

USB-C port on Raspberry Pi 4 is busy by DJI drone controller connection, so need to made a custom USB cable with additional part for power.
