Micoair 915MHz 30KM Long-Range LoRa Telemetry for Drones and Robotics/ LR900-F/Data Transmit Module for Pixhawk/Ardupilot/PX4

These modules worked exactly as they were expected to work. I was able to download the configuration app and make changes. They find each other immediately and work as if the serial port was directly connected to the computer.

Great long range telemetry and serial link

Very poor quality. USB c port on one of the units is loose and unit loses power at the slightest movement.

thanks

Buy the mainstream brands for this half-baked telemetry stuff. There are no support options, there is an "application" to download and to set it up but there is zero instructions and none of the options can be selected. The app barely works other then to send TEXT out the comport at regular intervals.No settings can be tailored. Example: App Defaults to 115K Baud but the devices are cofigured somehow to 57K out of the box. App can't even read the device to identify it as its own brand.No way to "bind" these. Looks hard coded for binding with the same unit. The app is just a COM tool with buttons that don't work.No Firmware updates, No manuals, No settings or config options, No pinouts (The Amazon Order Item info is about it for details).
