UBlox NEO 6M GPS Module with EEPROM

UBlox NEO 6M GPS Module with EEPROM provides a high-performance positioning solution for hobbyists and industrial designers who require accurate geographic data in a compact form factor. This module utilizes the proven u-blox 6 positioning engine to deliver exceptional sensitivity and acquisition times, even in challenging environments. Furthermore, the integration of an on-board EEPROM allows the device to store configuration settings and battery-backed RAM data, which facilitates faster “warm starts” after power cycles. Consequently, you can achieve a reliable GPS lock within seconds, making it an ideal choice for time-critical navigation tasks. Therefore, this module serves as a robust foundation for any project requiring real-time tracking, speed sensing, or precision time-syncing.

Key Features:

• High Sensitivity: Features a -161 dBm tracking sensitivity, allowing for reliable signal reception even in urban canyons or under dense foliage.
• Integrated EEPROM: Stores user-defined configurations and GNSS data permanently, ensuring the module retains its settings without a constant power source.
• Built-in Battery Backup: Includes a small rechargeable cell or supercapacitor to maintain the Real-Time Clock (RTC) and satellite orbit data for rapid re-acquisition.
• Ceramic Patch Antenna: Comprises a high-gain 25 x 25 mm ceramic antenna that connects via a U.FL connector, providing excellent signal-to-noise ratios.
• UART Communication: Utilizes a standard serial interface, which makes it compatible with almost any microcontroller, including Arduino, ESP32, and Raspberry Pi.
