Usage Tips:

• Power Supply: Make sure to use a 3.7V-4.2V battery or a stable 5V supply to power the module, as low voltage may affect communication and GPS accuracy.
• Antenna Placement: Ensure the GPS antenna has a clear line of sight to the sky for optimal satellite reception. For GSM, place the antenna in a location with good cellular signal reception.
• Communication Protocol: Use UART (Serial) communication for easy integration with most microcontroller boards, such as Arduino and Raspberry Pi.
• GPS Fix Time: Allow the module some time (typically 30-60 seconds) to get a GPS fix when initially powered up. This time may vary depending on the environment and the number of visible satellites.
