The 7Semi LC29HDA Dual-Band Multi-GNSS RTK Board is a high-precision positioning solution based on the Quectel LC29HDA GNSS module. It supports multiple satellite constellations, including GPS, Galileo, GLONASS, BeiDou, QZSS, using dual-band GNSS reception for reliable positioning.
With RTK positioning, the board provides horizontal accuracy down to 1 cm + 1 ppm under specified conditions, making it suitable for applications that require precise location data. It supports NMEA 0183 and RTCM 3.x protocols for standard GNSS data and RTK correction information.
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.
