Matek SAM-M8Q GPS

Every time you send your long range FPV drones up in the air on long range missions, you're taking risks. But there are ways to minimize your risks like installing a GPS unit, or a standalone buzzer unit on the drone. Those measures will help track your drone if and when it goes down. Matek SAM-M8Q is a low-cost preventive measure that you will want to install on your long range FPV drones.
