L76K GNSS Module For Raspberry Pi Pico, GPS / BeiDou (BDS) / GLONASS / QZSS, A-GNSS Compatible

Waveshare 31752 - L76K GNSS Module For Raspberry Pi Pico, GPS / BeiDou (BDS) / GLONASS / QZSS Support, Supports A-GNSS Function Features The Pico-GPS-L76K is a GNSS module designed for Raspberry Pi Pico, supports GPS, BeiDou (BDS), GLONASS and QZSS systems, allows multi-system combined or single-system independent positioning. Supports AGNSS function, and offers advantages such as fast positioning, high accuracy, and low power consumption. Combined with the Raspberry Pi Pico / Pico 2, it's easy to use global navigating function. Standard Raspberry Pi Pico header, supports Raspberry Pi Pico series boards Supports Multi-GNSS systems: GPS, BeiDou (BDS), GLONASS and QZSS Built-in Low-Noise Amplifier (LNA) for improved reception sensitivity Built-in SAW Filter for enhanced noise reduction performance Supports AGNSS UART communication baudrate: 4800~115200bps (9600bps by default) Onboard battery holder, supports ML1220 rechargeable cell, for preserving ephemeris information and hot starts 4x LEDs for indicating the module operating status Comes with online development resources and manual (Raspberry Pi Pico C/C and MicroPython examples) Specifications GNSS parameters GNSS GPS/GLONASS/BDS/QZSS Chip Platform AT6558R L1 Band Receiver(Channels) 32 tracking ch/ 72 acquisition ch L1 Band ReceiverSBAS N/A A-GNSS Support Sensitivity（Acquisition） -148dBm Sensitivity(Re-acquisition) -160dBm Sensitivity(Tracking) -162dBm TTFF (Time to first fix)Cold starts 30s, Autonomous 5.5s, With AGNSS TTFF (Time to first fix)Hot starts 2s Position accuracy 2.0m CEP Speed accuracy 0.1m/s Acceleration accuracy(Max) 0.1m/s² Timing accuracy 30ns Others Communication interface UART Baudrate 4800~115200bps (9600bps by default) Update rate 1Hz (default), 5Hz (max) Protocols NMEA 0183, CASIC Proprietary Communication Protocol Power supply voltage 5V  Overall current consumption < 40mA@5V (Continue mode) Operating temperature -40℃ ~ 85℃ Dimensions 55.95 × 21.00 (mm) What's on board L76K module Battery holdersupports ML1220 rechargeable cell, for preserving ephemeris information and hot starts GNSS antenna connector Raspberry Pi Pico header Standby mode switch GNSS configuration button RT9193-33power chip Status indicatorsRXD/TXD: UART TX/RX indicatorPPS: GPS status indicatorPWR: power indicator Pinout definition Outline dimensions Wiki: www.waveshare.com/wiki/Pico-GPS-L76K Package Content Pico-GPS-L76K x1 GPS Antenna x1
