Raspberry Pi 4B

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

  • Two micro-HDMI outs, only one available 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 only on this display.
  • 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 DJI RC-N1/RC-N2/RC-N3 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 RC-N1, RC-N2 or DJI RC-N3 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 RC-N1/RC-N2/RC-N3 connection, so need to made a custom USB cable with additional part for power.

Changing camera type

In Cosmostreamer system terminology, a camera is any device that Cosmostreamer can work with. DJI Pocket, DJI Osmo, Goggles - this all a "camera".
MicroSD image with Cosmostreamer configured for "DJI Goggles2/Integra" by default, so needed to change a "camera type".

  2. Go to chapter "Info"
  3. Choose camera type "DJI Fly drones"
  4. Don't forget to click "Save" button.




License key

License key is a text string, unique for each Raspberry Pi. Each camera type needs different license keys. It's possible to install multiple amount of license keys on one device and use this device for some camera types, i.e. Pocket Osmo, Pocket 2, and others. Need to buy license for correct operation process.

  1. Buy license key on a product page
  2. Make a photo of HDMI display or screenshot of the app with a QR image and send it in email on cosmostreamer@gmail.com for making a license key
  3. When you got a license key - use web interface or CosmoViewerNG application, menu "device settings" -> "License" and insert license key into field. And click "Install license" button.




DJI RC-N1, RC-N2 and RC-N3 connection

DJI RC and DJI RC2 are not supported!

Use any USB-C to USB-C cable and plug one side to Raspberry Pi USB-C port, second side - to USB-C port on DJI RC-N1/RC-N2/RC-N3. The same USB-C which is used for smartphone connection.
