Grove - GPS (Air530Z)

Confused about your GPS not working well in urban or outsides under only one or a few satellite module? Then you should not miss our new Seeed Grove - GPS (Air530Z).

It’s a high-performance, highly integrated multi-mode satellite positioning and navigation module to use with Arduino and compatible boards. It supports GPS / Beidou / Glonass / Galileo / QZSS / SBAS, which makes it suitable for GNSS positioning applications such as car navigation, smart wear, and drone. This module is capable of receiving more than 6 satellites at the same time and is able to work excellently even if there's a very bad signal.

Grove cable included!

We are now shipping the updated Air530Z version, which uses an updated version of the chip.

Features

• High precision Positioning: Positioning error within 10 meters, and will still be accurate with a bad signal
• Integrated RF Baseband Design: Adopt the integrated design of RF baseband, which integrates DC/DC, LDO, LNA, RF front-end, baseband processing, 32-bit RISC based chip, RAM, FLASH storage, RTC, and power management functions
• Low Power Consumption: Low power consumption at only 31uA
• High Compatibility: Compatible hard/soft interface for other modules
• Product number: Seeed 109020022
