Waveshare L76B GNSS Module for Raspberry Pi Pico, Support GPS, BDS, QZSS, L76B

Features B>
PICO-GPS-L76B is a GNSS module designed for Raspberry PI PIO, supporting multi-satellite systems including GPS, BDS and QZSS. It has advantages such as fast positioning, high precision and low power consumption, etc. Combined with Raspberry Pi PIO, it is easy to use the global navigation function.
1. Standard Raspberry Pi PIO header, support Raspberry Pi PICO series boards
2. Support multi satellite systems: GPS, BDS and QZSS
3. Easy prediction technology, self-help, help for rapid positioning
4. Power supply, intelligent periodic mode controller for energy saving
5. Support D-GPS, SBAS (WAAS/EGNOS/MSAS/GAGAN)
6. UART Communication Baudrate: 4800 ~ 115200bps (9600bps by default)
7. Support on-board battery, support ML1220 rechargeable cell, to preserve ephemeris information and hot starts
8. 4 X LEDs to indicate the operating status of the module
9. Comes with development resources and manual (Raspberry PI PIO C/C++ and Micropython examples)
