Taidou n303-3 module GPS Beidou or gloanss dual mode positioning compatible with 6m / 7m / m8n
N303-3 module is a dual-mode navigation and positioning module which supports BDS biagps Li / L frequency point two out of three. The module integrates a new generation of td1030 which can support bdsbl / GPS Li / glonassl frequency point SOC baseband + RF integrated chip td1030, which provides high sensitivity, low power consumption and low cost positioning / navigation solutions for vehicle and ship borne navigation terminal products. The size of n303-3 module is 16mmx12.mmx22mm, which meets the requirement of module volume reduction in the design of positioning terminal products. The module is packaged with 24pin stamp hole, which can meet the requirement of fast mounting module in the production of positioning terminal products. N303-3 has integrated antenna detection circuit, power management function and built-in LNA + saw
24pi stamp hole package, size 16mmx122mx2.2mm, supports BDS Bi / GPS Li / GLONASS L1 frequency point, supports the following six working modes, and can switch between each other through commands
1) Single BDS Bi operation mode
2) Single gpsl operation mode
3) L1 glons single mode
4) BDS Bi / gpsl dual mode operation mode (default mode)
5) GLONASS Li / BDS Bi dual mode operation mode
6) GLONASS Li / GPS Li dual mode operation mode
The on-chip LNA covering three frequency points of BDS Bi / GPS Li / GLONASS Li is built in the chip, which supports the power supply to the active antenna, and has the functions of antenna status detection and antenna short-circuit protection
With backup power input interface,
Support hot support external reset
The average power consumption is about 25maa3.3v
Wide voltage input range, 2.7 ~ 3.6V
High sensitivity, high positioning accuracy, high integration, simple peripheral application circuit
