recommend the updated version: M5Stack GPS/BDS Unit with SMA Antenna (AT6668) Relevant Information: Comparing GPS/BDS Unit v1.1 and Unit-GPS SMA GPS Unit v1.1 is a GNSS Global Positioning System navigation unit that integrates CASIC's high performance navigation chip AT6668 and signal amplifier chip MAX2659, with a built-in ceramic antenna, providing more accurate and reliable satellite positioning services. Compared with previous products, AT6668 supports multi-frequency and multi-mode GNSS signal reception, receives signals from multiple satellite navigation systems (including GPS, BD2, BD3, GLONASS, GALILEO and QZSS), and supports multi-system combined positioning as well as single-system stand-alone positioning. It has enhanced anti-jamming capability and higher positioning accuracy, allowing it to quickly acquire high-precision location information in areas with weak signals. This module is widely used in high-precision positioning applications such as in-vehicle positioning and navigation, IoT positioning devices, and more. Features Supports multiple satellite navigation systems (GPS/QZSS/BD2/BD3/GAL/GLO) Multi-frequency and multi-system reception Multi-channel Low power consumption 2x LEGO-compatible holes Programming platforms: Arduino, UIFlow, etc. Includes 1x Unit-GPS v1.1 1x HY2.0-4P Cable (20CM) Applications In-vehicle positioning and navigation Wearable devices IoT positioning devices Drones Portable devices Public transportation station reporting Specifications Specification Parameter SoC AT6668 Supported Systems GPS/QZSS/BD2/BD3/GAL/GLOFrequencies:BDS: B1I+B1CGPS/QZSS/SBAS: L1GALILEO: E1GLONASS: R1 Channels 50 channels Communication UART communication, default 115200bps@8N1 Positioning Accuracy
