ATGM336H-5N, GNSS Module support BDS (BeiDou Navigation Satellite System)

ATGM336H-5N is a BDS/GNSS Whole Constellation Positioning And Navigation Module.

The BeiDou Navigation Satellite System (BDS) (北斗卫星导航系统) is a Chinese satellite navigation system.

reference: Wikipedia - BeiDou

The ATGM336H-5N series of module, package size for the 9.7mmX10.1mm is a
general term of high performance BDS/GNSS whole constellation positioning and
navigation module series.The series of module products are based on the fourth
generation low power consumption GNSS SOC single chip of Zhongke micro -
AT6558,support a variety of satellite navigation systems, including the Chinese BDS
(Beidou satellite navigation system), American GPS, Russian GLONASS, EU Galileo,
Japanese QZSS and Satellite enhanced system SBAS (WAAS,EGNOS,GAGAN,
MSAS)). AT6558 is a real sixes in one multi-mode satellite navigation and
positioning chip, including 32 tracking channels, can simultaneously receive GNSS
signals of six satellite navigation systems and implement joint positioning, navigation,
and timing.

ATGM336H-5N series of modules have high sensitivity, low power, low cost and
other advantages, suitable for vehicle navigation, handheld positioning, wearable
devices and you can directly replace the LEA series modules of Ublox. 

To first test the ATGM336H-5N module. I install Ublox's u-center on Windows, connect the module using a FTDI FT232RL USB to Serial board.

Connection between ATGM336H-5N and FT232RL
VCC(ATGM336H-5N) <---> VCC(FT232RL)
GND(ATGM336H-5N) <---> GND(FT232RL)
TX(ATGM336H-5N)    <---> RX(FT232RL)
RX(ATGM336H-5N)    <---> TX(FT232RL)

Install and run Ublox - u-center (GNSS evaluation software for Windows)
