Dual Band GPS Module With L1 L5 Positioning Technology GNSS Expansion Board And RTK Function For Ultra Precise City Navigation And Performance Ready LC29H AA GPS RTK HAT

Dual Band GNSS RTK GPS Module for precise city navigation
✔️ L1/L5 dual-band, multi-GNSS support, RTK enabled for cm-level

The GPS RTK HAT is a dual-band GNSS expansion board designed for a 40-pin GPIO interface. It tracks L1 and L5 signals and supports GPS, BDS, GLONASS, Galileo, and QZSS, with SBAS options (WAAS, EGNOS, MSAS, GAGAN) to boost performance. It includes EASY technology for faster TTFF using stored ephemeris/almanac data and a built-in low-noise amplifier with an acoustic filter for strong urban-signal reception.
