GPS+BDS Beidou Dual-Mode Module - ATGM336H Replacement Satellite Positioning Navigator for Flight Control Systems, NEO-M8N Compatible

Build more capable positioning projects with this GPS + BeiDou Dual-Mode GNSS Module, designed for satellite navigation, flight-control applications, robotics, vehicle navigation, and other embedded positioning systems. Based on the AT6558 GNSS SoC, the ATGM336H-5N series supports multiple global satellite navigation systems for flexible positioning, navigation, and timing applications.

The module supports BDS (BeiDou), GPS, GLONASS, GALILEO, QZSS, and SBAS, with up to 32 tracking channels for multi-system satellite reception. It communicates primarily through UART using NMEA0183 protocol, making it suitable for integration with compatible microcontrollers and embedded systems.

With low power consumption and built-in antenna detection and short-circuit protection, this compact module is a practical option for DIY electronics, robotics, navigation equipment, and projects requiring reliable satellite positioning.
