1. Multi System GNSS Support: The L76K GNSS module supports GPS, BeiDou (BDS), GLONASS, and QZSS. It allows multi system combined positioning or single system operation for better accuracy and reliability.
2. Improved Sensitivity and Performance: Equipped with a low noise amplifier (LNA) and SAW filter, the module boosts reception sensitivity and reduces noise, ensuring reliable performance in various environments.
3. A-GNSS Function: The module supports Assisted GNSS (A-GNSS) for faster positioning, reducing first time fix delays, especially in challenging locations.
4. Versatile Communication and Power: It supports UART communication with baud rates from 4800 to 115200 bps (default: 9600 bps). It also has an onboard battery holder for an ML1220 rechargeable battery to store ephemeris data and enable hot starts.
5. Easy Integration and Development: Compatible with support for Pi Pico series, the module comes with full online resources, including C/C++ and MicroPython development guides and example code, making integration into projects simple.
