GNSS Module for Raspberry Pi Pico (L76B)

Use your Raspberry Pi Pico for global navigation and positioning! This is an L76B-based GNSS module designed for the Raspberry Pi Pico, with multi-satellite system support including GPS, BDS, and QZSS. The board comes complete with a matching GPS antenna. This Pico HAT offers fast positioning, high accuracy and low power consumption. The board includes an ML1220 rechargeable battery holder, which allows the module to preserve ephemeris information and hot starts. Do not use a standard non-recharagable CR1220 battery in this board! Your Pico slots into the pre-soldered female headers and the online resources help you get started quickly and easily, including example code. Raspberry Pi Pico not included. You'll need a Pico with male headers soldered to it. You can grab a Pico here and Pico male headers here, or buy a Pico with pre-soldered headers. Features
