DFRobot GPS + BDS BeiDou Dual Module

The GPS and BeiDou module from DFRobot is based on the AT6558 chip and receives the satellite systems BDS, GPS, GLONASS, Galileo, QZSS and SBAS. It delivers position and time as NMEA data via UART, 9600 baud by default, and works with Arduino, Raspberry Pi, STM32, ESP32 and ESP8266. A backup battery on the board stores the satellite data and speeds up the warm start.

Recommended Accessories:

• Dupont Cable M-F 20cm 20 Pieces

Features:

• Several satellite systems at once: BDS, GPS, GLONASS, Galileo, QZSS, SBAS
• Up to 32 tracking channels, A-GNSS
• SMA and IPEX antenna connections, ceramic antenna with IPEX cable included
• EEPROM for the settings, XH414 backup battery for a fast warm start
• Antenna detection and antenna short-circuit protection
• PPS pulse output for precise time

Application Examples:

• Position and time for Arduino and ESP32 projects
• GPS loggers and trackers
• Navigation of drones and vehicles
