L76K GNSS Module for Raspberry Pi Pico

This add-on for your Raspberry Pi Pico supports GPS, BeiDou (BDS), GLONASS and QZSS systems, allows multi-system combined or single-system independent positioning. The board offers fast positioning, high accuracy, and low power consumption, and supports AGNSS (Assisted GNSS), a technology that dramatically speeds up and improves satellite positioning by downloading critical orbital data via mobile networks or Wi-Fi rather than slow satellite links. It has a built-in Low-Noise Amplifier (LNA) for improved reception sensitivity, and built-in Surface Acoustic Wave (SAW) Filter for enhanced noise reduction performance. There is a holder for an ML1220 rechargeable battery (battery not included - do not use single use batteries!), for preserving ephemeris information and hot starts. Four LEDs indicate the module operating status. The board comes with a separate GPS antenna (see images). Raspberry Pi Pico not included. What's Onboard?
