L76K GNSS module for Pico
GNSS module based on L76K, designed for Raspberry Pi Pico
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 / , 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 baud rate: 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)
