GPS+BDS+GLONASS dual mode ATGM336H GPS timing module GP-02
1. Product Overview
GP-02-Kit is a highly integrated SOC development board with ceramic antenna and high
performance BDS/GNSS multi-mode satellite navigation receiver. The main chip is AT6558R
satellite positioning chip. Integrated radio frequency front end, digital baseband processor,
32-bit RISC CPU, power management and active antenna detection and protection functions.
Support a variety of satellite navigation systems, including China’s BeiDou Navigation
Satellite System (BDS), the United States’ GPS, and Russia’s GLONASS, which can realize
multi-system joint positioning.
GP-02-Kit follows the NMEA protocol and sends instructions through serial communication to
control the work content of the development board.

6. Design guidance
6.1. power supply
The recommended voltage is 5V.
6.2. Use of GPIO
The development board is connected to the RX communication interface to access the 22Ω of
the TX, and it has continued to rush

Notice
Adjust the balance time to ensure the rationalization of the gas when the solder paste melts. If
there are too many gaps on the PCB, the equilibration time can be increased.
Considering that the product is placed in the welding area for a long time (the temperature is
above 180°C), in order to prevent damage to the components and the bottom plate, the
placement time should be shortened as much as possible.
