Description

The GPS Module v2.0 is a high-performance GNSS positioning module built around the AT6668 chip for accurate and reliable satellite positioning. It supports multi-frequency and multi-mode GNSS reception across GPS/QZSS, BD2, BD3, GLONASS, GALILEO, and QZSS, enabling multi-system joint positioning or single-system independent positioning with strong anti-interference capability.

The GPS Module v2.0 includes an external active GPS/BD antenna with a 1 m cable, a DIP switch for flexible TX/RX and PPS pin routing, and PPS output for precise timing. It is designed for stackable M5Stack host systems and is suitable for navigation, IoT positioning, remote monitoring, smart city, home automation, and industrial automation projects.

Notice: This product is EOL (End of Life). For new designs, consider Module GPS v2.1 as the newer version.

When used with the Basic host, G12 is a strapping pin during startup and must remain low; switching it ON during startup may prevent the device from booting. G25 is shared between PPS output and the speaker input, and Core2 shares G2 with the speaker pin, so only one of the conflicting functions should be used at a time.

Features

  • GPS Module v2.0 supports GPS/QZSS, BD2, BD3, GALILEO, and GLONASS positioning systems.
  • Multi-frequency, multi-system GNSS reception with 50 channels.
  • Positioning accuracy below 1.5 m (CEP50) and update rate up to 10Hz.
  • External active GPS/BD antenna through an SMA connector.
  • PPS signal output for precise timing applications.
  • DIP switch routing for selectable UART and PPS pin groups.
  • Supports module stacking and development with UiFlow1, UiFlow2, and Arduino IDE.

Other Content

The GPS Module v2.0 uses switchable M5-Bus pins marked SW to adapt GNSS_TX, GNSS_RX, and PPS routing to different host controllers. Before development, confirm the host model, DIP switch positions, and firmware pin configuration so the selected UART and PPS signals match the application.

Compared with the earlier Module GPS based on NEO-M8N, the GPS Module v2.0 adds DIP switch pin routing and improves positioning accuracy from 2.5 m to 1.5 m in the product comparison data.
