7Semi L89HA Breakout Multi-GNSS engines for GPS, IRNSS, GLONASS, BeiDou, Galileo and QZSS

The 7Semi L89HA Breakout is a high-performance Multi-GNSS module that supports six satellite systems — GPS, IRNSS (NavIC), GLONASS, BeiDou, Galileo, and QZSS. It is built on the Quectel L89 chipset and designed for precise, reliable, and fast positioning. The breakout board integrates dual antennas (patch and chip), supports both UART and I2C communication, and includes a backup power input for maintaining satellite data and faster re-acquisition. It offers exceptional sensitivity and accuracy, making it ideal for navigation, tracking, and IoT applications.
