Features

(applicable to the latest release)

• Supports Pi A+, Pi1B+, Pi2B, Pi3B (Pi3B+ not at the moment), Pi Zero, Pi Zero W, Odroid-W, Pi V1 and V2 cam (NOTE: GroundPi needs to be atleast a Pi2)
• Maximum possible resolutions (depending on cam used): 1280x720p 60fps 1296x972p 42fps 1640x922p 40fps 1920x1080p 30fps
• Maximum possible video bitrate about 12Mbit
• Latency ~125ms with 720p 48fps default settings, minimum possible latency roughly around 110ms
• Support for 2.3/2.4/2.5Ghz bands and 5.2Ghz to 5.8Ghz bands
• 2.4Ghz on 3dbi omni antennas: About 1-1.5km range with ~70mw wifi sticks, about 2-3km with ~300mW high-power cards (with default settings, about 50% higher range is possible with lower bitrate "longrange mode")
• 5Ghz on 3dbi omni antennas: ~250m range with 25mW wifi sticks, about 1km range with ~300mW high-power cards
• Configuration can be done from Windows, no Linux knowledge required
• Supports different configuration profiles selectable on the field via jumpers or DIP switches
• Forwarding of video stream and telemetry data to 2nd display via: USB Tethering, Wifi Hotspot, Ethernet, Wifibroadcast relay mode
• Bi-directional mavlink telemetry support (uplink not 100% compatible with all FCs yet)
• Support for video and telemetry inside Tower App, QGroundcontrol, Mission Planner
• Fully dynamic and automatic detection of 2nd display, just plug it in or connect via Hotspot and it'll work
• 2 wifi sticks transmit diversity on two different frequencies for bulletproof videolink
• 3 wifi sticks receive diversity support for Atheros, 5 wifi sticks receive diversity support for Ralink (or 2x Atheros and 2x Ralink)
• Integrated high resolution fully customizeable OSD with support for Mavlink, Frsky, LTM, Smartport telemetry
• .AVI Ground recording, PNG screenshots and telemetry data automatically saved to USB stick
• Automatic graphing of RSSI, packetloss, video bitrate and other data
• Quick startup, about 10 seconds until video is shown
• No issues as with standard wifi, no disconnection, video freeze etc, video will quickly recover
• Live and responsive RSSI display with defective blocks and packetloss display
• Handling similar to analog gear, just switch on and fly
• Smooth and stutter-free video (thanks, mmormota)
• Video reception is very stable even in difficult multipathing environments, no constant glitching as with analog
• OSD overlay rendered on the receiver will stay clear and functional even if video is too bad to fly
• SD card reliability and general robustness tweaks (read-only filesystem, syslogging to SD disabled, etc.)
• Debug logs and screenshot will be saved to sdcard in case of errors
• Low-latency/high update-rate RC over wifibroadcast via Joystick (Atheros only)
