The 7Semi LC29HEA GNSS Development Board is a high-precision dual-band positioning solution built around the powerful Quectel LC29HEA multi-constellation GNSS module. Designed for advanced navigation, real-time tracking, robotics, UAVs, autonomous systems, and precision positioning applications, this compact board supports simultaneous reception of GPS, GLONASS, Galileo, BDS, QZSS, and satellite systems for improved accuracy and signal reliability.
Featuring dual-frequency L1 + L5 GNSS reception, the board significantly reduces multipath interference and improves positioning performance even in dense urban environments. With RTK capability support, the module can achieve centimetre-level positioning accuracy for professional-grade applications. Integrated USB connectivity, UART pins, Qwiic interface, PPS output, reset control, and SMA antenna connector make the board easy to integrate into embedded systems and development environments.
The 7Semi LC29HEA board is ideal for developers and engineers building high-accuracy navigation systems, drone applications, surveying tools, smart agriculture devices, industrial automation platforms, and IoT tracking systems requiring dependable GNSS performance with low power consumption.
