Automatically enters working mode after power-on process. Operates within a specified voltage range for optimal performance. Requires correct wiring according to the diagram to prevent short-circuiting. Should be away from motors and power lines to avoid interference. Uses -84 coordinate system for accurate positioning. 1. When the module is powered on for the first time, it automatically go through the power-on process internally and GP10 enter the working mode. 2. Please supply power to the module according to the voltage within the specified range. 3. Please connect the wires correctly according to the wiring diagram to avoid short-circuiting and burning the module. 4. When using the module, please keep it away from motors, power lines and other interfering parts. 5. GP10 module and longitude coordinate system is -84, the map is other coordinate system, you need to do coordinate system conversion to use. Otherwise, the positioning error becomes large. 6. In order to the best results of the product, each module has to be debugged with ceramic antenna before leaving the factory, so there be some scratches. However, each module is a normal qualified product, please to use! Color: Black Material: plastic Package Contents: 1*set of Module Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
