1. This product is a GNSS (Global Navigation Satellite System) expansion board suitable for Pico based on the L76B module. It supports GPS, Beidou (BDS) and QZSS multiple satellite systems, with fast positioning, accurate positioning and low power consumption. advantage. With Pico, it can easily realize global positioning. 2. Onboard Pico interface, suitable for Pico series motherboards. 3. Support GPS, Beidou (BDS) and QzSS multiple satellite systems. 4. Support EASY self-generated Track prediction function, which can realize fast positioning. 5. Support Alwayslocate function, which can realize intelligent control of periodic mode. 6. Support D-GPS, SBAS (WAAS/ EGNOS/MSAS/ GAGAN). 7.Support serial port communication baud rate range: 4800-115200bps (default 9600bps). 8. Onboard battery holder, can be connected to ML1220 rechargeable battery, used to save ephemeris data and hot start. 9.There are 4 LED indicators on board, which is convenient to check the running status of the module GNSS parameters Signal frequency band: GPS L1 (1575.42mhz) BD2 B1 (1561.098MHz) Number of channels: 33 tracking channels, 99 acquisition channels and 210 channels C/A code SBAS: WAAS, EGNOS, MSAS, GAGAN Horizontal positioning accuracy (autonomous positioning): less than 2.5m First positioning time@-130dBm Cold start: less than 15s Warm start: less than 5s Hot start: less than 1s Capture: -148dBm Sensitivity tracking: -163dBm Reacquisition: -160dBm Altitude (max): 18000m Dynamic performance: Speed (max): 515m/s Acceleration (max): 4g Communication interface: UART Serial port baud rate: 4800-115200bps (default 9600bps) Update rate: 1HZ(default), 10HZ(max) Communication protocol: NMEA 0183, PMTK Power supply voltage: 5v Working current: 13MA Whole machine current consumption: less than 40mA@5v (Continue mode) Working temperature: -40c~85C Colour: blue Material: PCB+metal Size: 52 x 21mm Package Contents: 1 x GNSS expansion board Only the above package content, other products are not included.
