The 7Semi LC29HBA GNSS Development Board is a high-precision L1 + L5 dual-band RTK GNSS solution supporting GPS, GLONASS, Galileo, BeiDou, QZSS. It delivers centimeter-level positioning with reliable performance for surveying, robotics, UAVs, precision agriculture, and navigation applications.
The board provides UART and I²C interfaces, along with a Qwiic-compatible connector for easy integration with microcontrollers and embedded systems. Its compact design makes it suitable for robotics, surveying, precision agriculture, autonomous systems, mapping, and other high-accuracy positioning applications.
Key Features
- L1 + L5 Dual-Band GNSS for improved positioning performance.
- Dead Reckoning (DR): Maintains continuous positioning during temporary GNSS signal loss using external motion and vehicle sensor data.
- Multi-GNSS Support: GPS, GLONASS, Galileo, BeiDou, QZSS
- Centimeter-Level RTK positioning for high-precision applications.
- Multipath Mitigation for improved performance in challenging environments.
- High Sensitivity with integrated LNA and diplexer.
- NMEA 0183 & RTCM 3.x protocol support.
- USB, UART, Qwiic, PPS & SMA connectivity for easy integration.
