Description

The Siderion SP0700 is an affordable, compact, and high-precision triple-band L1/L2/L5 GNSS RTK (Real-Time Kinematic) device. Powered by the latest generation of u-blox ZED-F20P modules, the SP0700 supports concurrent reception of GPS, Galileo, BeiDou, QZSS, and NavIC signals. Consequently, the device delivers reliable performance and fast convergence, achieving centimeter-level accuracy in seconds. Its 2mm pitch castellated holes make it ideal for being soldered onto your own custom boards and designs. The SP0700 operates across a temperature range from -40°C to +70°C.

UART2 Port

SPI Port

The SPI port is available only when the D_SEL pin is pulled LOW.

The USB port can be used only when the UART1 or SPI ports are not used, and vice versa.
