Module GPS v2.0

SKU:M003-V2

Description

Module GPS v2.0 is a high-performance GNSS global positioning module, featuring the ATGM336H navigation module from Zhaokong Microelectronics, integrated with the high-performance AT6668 chip to provide precise and reliable satellite positioning services. This module supports multi-frequency, multi-mode GNSS signal reception and is compatible with various satellite navigation systems, including GPS, BD2, BD3, GLONASS, GALILEO, and QZSS, enabling high-precision, multi-system joint positioning or single-system independent positioning, and offering excellent anti-jamming capabilities. In weak signal areas, it can quickly acquire higher precision positioning information.
The module comes equipped with an external SMA antenna, and also features a dip switch to allow users to flexibly switch TX/RX communication pins, with PPS signal output for precise timing adjustments. It supports multi-stack usage, offering more customization and flexibility, making it suitable for high-precision positioning applications such as in-vehicle navigation, IoT positioning devices, remote monitoring, smart cities, and home and industrial automation.

Dip switch pin

When the Basic host is used, when starting up, the G12 pin is used as the Strapping pin. The boot must be set low and cannot be switched to the ON end, otherwise it cannot be switched ON normally. After the boot is normal, it can be used with other pins normally and can be switched to the ON end. G25 pin as a PPS pin output function, and the speaker for the input function, resulting in functional conflict, can only be used one of two.
When used with Core2, the G2 pin and the speaker pin are multiplexed, and can only be used as one of two choices.
