UAV Link List

A list of open-source projects for radio links with UAVs.

Multipurpose Link

• DroneBridge
  • "One link to rule them all"
    • Telemetry: Bidirectional MAVLink, LTM depreciated
    • RC: 12 channel. Current version (0.7) has high latency.
    • Video: up to 1080p, OSD, 110ms latency
  • Uses wifibroadcast
  • Range 0.3 - 14+ km (0.5-2km typical)
  • Companion Android app
  • Hardware:
    • RPi to RPi
    • Single ESP32 (no video). Web interface.
• OpenHD
  • Multifunction link
    • Telemetry: Bidirectional MAVLink (uplink dependent on FC support)
    • RC: Supports MAVLink or MSP/SUMD/IBUS/XBUS
    • Video: 720p/60 to 1080p/30 (max 12Mb/s), 125ms typical
