Note: 1. This product has a protection mechanism. The GPS antenna should be placed outdoors where it can receive a signal. It is not recommended to use it indoors, as it will restart if it cannot receive a GPS signal.
2. The machine does not have a built-in LPF. If players need to reduce harmonic interference, you need to use your own LPF.
3. Do not use fast chargers or chargers with fast charging protocols, as this may damage the chip. A standard 5V power supply is sufficient.
