LinkIt MT3332 Module is a low-cost and low-power consumption GNSS module. The module can simultaneously acquire and track multiple satellite constellations that include GPS, GLONASS, GALILEO, QZSS and SBAS. Based on our experienced design, this module fully exhibits the excellent performance of MT3332 chip. It works in GNSS signal difficult environment, providing fast acquisitions and excellent tracking performance.
