During the processing of this product, the ceramic antenna may be worn to the point that it is normal. The product is brand new, so please don’t shoot if you mind. (Domestic chip)

Main parameters:

1. The default baud rate of this module is 9600.

2. The power supply voltage is 3.3v-5v (5v or 3.3v power supply can be directly connected, and the core working voltage is 3.3v).

3. It can be directly connected to 3.3v or 5v microcontroller I0 for communication.

Product features:

1. The module adopts U-BLOX NEO-6M module, which is small in size and excellent in performance.

2. The module adds amplifying circuit, which is conducive to the fast search of satellites by the passive ceramic antenna.

3. The module can set various parameters through the serial port, and can be stored in EEPROM, which is easy to use.

4. The module has its own SMA interface, which can be connected to various active antennas with strong adaptability.

5. The module is compatible with 3.3V/5V level, which is convenient to connect to various single-chip systems.

6. The module comes with a rechargeable backup battery.

Note: After the main power supply is disconnected, the backup battery can maintain GPS ephemeris data for about half an hour to support warm start or hot start, so as to achieve rapid positioning.
