Pocket-Groundstation

The Pocket-Groundstation is a mini ground station that will accept any Fatshark module. Project updates > https://github.com/skaman82/Pocket-Groundstation/blob/master/updates.md

Features: • takes 2S to 4S voltage • 3,5mm AV output • RJ45 output for power+AV (only one wire to goggles) - constant 8V output on any power source • Powerswitch • Build-in DVR • Automatical switching between DVR output (to adjust settings or review footage) or direct module output • Low-voltage alarm and cell autodetection (adjustable via OLED, so it can work with lipo or li-ion batteries) • DRV-control via OLED (Eachine Pro DVR) • RSSI/Channel-information and DVR-Autostart (only with True-D module with 3.7D firmware)
