| Windows Ground station： | https://github.com/TalusL/fpv-wfb , https://github.com/OpenIPC/fpv4win |
| How to do? |
- Copy the key file(gs.key) to the installation directory of the ground station. - Double click to open the fpv4win program; - Select the correct Adapter(usually RTL8812AU), Channel (161 defaults, this Adapter only works in the 5.8GHz, and the available channels rangefrom 36 to 177), and Codec(H265 defaults, with high compression and low latency), - Click START to use it. |
| Android App(FPVue or PixelPilot): | https://github.com/gehee/FPVue_android/releases https://github.com/OpenIPC/PixelPilot/releases/tag/latest |
| How to do ? |
- First, install the app and then save the key file(gs.key) to your phone. - Open FPVue, find WFB-NG settings in the upper left corner settings menu; - Click gs.key, popp up the file manager, and find the previously saved key file - Then sett the Channel ((161 defaults, this Adapter only works in the 5.8GHz, and the available channels rangefrom 36 to 177 and Codec (H265defaults, with high compression and low latency), - And then plug in the Receive Adapter (or network Adapter). - The APP will prompt the current channel being used, and then it can be used normally |
| Ground stations |
Ground stations can also use SBC such as Raspberry Pi, Radxa zero3w, Orange Pi 5, etc., all of which have HDMII interfaces, so FPV goggles and VRgoggles can be used as displays, and the transmission delay can be better than that of mobilephones. Radxa zero3w is recommend for cost-effectiveness considerations |
| Ground station installation and configuration： | https://github.com/OpenIPC/sbc-groundstations/releases/tag/zero3w-v1.5.0 |
| In addition to using the OpenIPC firmware, this VTX can also flash the Rubyfpv firmware, which is richer in settings and functions than OpenIPC, but currently has slightly higher latency. | |
| Ground station is also recommended to use Radxa zero3w, firmware download: | https://rubyfpv.com/downloads.php |

https://github.com/OpenIPC/sbc-groundstations/releases/ https://rubyfpv.com/hardware.php This is aHDMI- receiver for Sphere link digital FPV system, and it's compatible with OpenIPC and Rubyfpv. If you choose the version with 1G RAM + 32G Micro SD, the OpenIPC image will be burned. You just need to plug in the HDMIdisplay or FPV glasses, power it on, set the channel, and you're ready to go. If you choose the version with 1G RAM , you need to prepare an 8G or larger micro SD card, and then use some software (like BalenaEtcher) to burn the image to the SD card. |
