Ublox NEO-6M GPS Module HW-539
The Ublox HW-539 NEO-6M GPS Module is a high-performance GPS receiver module designed for accurate positioning and navigation in various electronic applications. Built around the Ublox NEO-6M chip, this module offers excellent sensitivity, fast time-to-first-fix, and low power consumption, making it an ideal choice for technical writers documenting smart electronics projects. It features a built-in ceramic antenna or supports an external antenna, a backup battery for quick start-up, and EEPROM for storing configuration settings. The module communicates via a UART interface, enabling seamless integration with microcontrollers such as Arduino, Raspberry Pi, and other development platforms. Its compact design and robust performance make it suitable for both hobbyist and professional applications in navigation, tracking, and timing.
Features:
- Micro-USB Port Allows direct connection to PC.
- Status LEDs Power/fix indicators for easy signal lock feedback.
- External Antenna Interface SMA connector
- Able to use GPS as a really accurate clock, this board provides a PPS (pulse per second) signal. This is a highly accurate clock pulse coming off a pin on the GPS that NTP can use. If you have such a GPS the resource below is a must read.
- Compact and excellent performance
- Onboard ceramic passive antenna, able to search for the satellite in open area, and an external antenna is optional
- SMA port, convenient for connecting with the external active antenna, stronger satellite search ability
- A reserved TTL port, convenient for connecting to USB-TTL or external single chip microcomputer
