Stand Alone Wifi Module for H520 The Stand Alone Wifi allows you to fly the H520 without a camera, but still with full telemetry. The Ardupilot based Wifimodule transmits the data from the battery as well as the exact GPS coordinates to your ST16S. Through the module you are also able to upload all mission data to the H520. Through the practical adapter plates above and optionally below you have the possibility to make suitable attachments for the Stand Alone Wifi, non-manufacturer or own attachments. The two 5V outputs (BEC and USB) can be used as a power source. The lower carrier plate is additionally secured by a retaining wire.
