Onboard Interfaces

Overview

The Pico-GPS-L76B is a GNSS module designed for Raspberry Pi Pico, with multi-satellite systems support including GPS, BDS, and QZSS. It has advantages such as fast positioning, high accuracy, and low power consumption, etc. Combined with the Raspberry Pi Pico, it's easy to use the global navigating function.

Features

  • Standard Raspberry Pi Pico header supports Raspberry Pi Pico series boards
  • Multi-satellite systems support: GPS, BDS, and QZSS
  • EASY, self-track prediction technology, help quick positioning
  • AlwaysLocate, intelligent controller of periodic mode for power saving
  • Supports D-GPS, SBAS (WAAS/EGNOS/MSAS/GAGAN)
  • 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
