u-blox ZED-X20P evaluation board for high-precision GNSS/RTK

Socials
simpleRTK4 Optimum

The simpleRTK4 Optimum from ArduSimple is a u-blox ZED-X20P evaluation board for centimeter-level positioning accuracy. Designed for UAVs, UGVs, robotics, and autonomous systems, it simplifies RTK integration with a versatile, shield-compatible design.

With multi-band, multi-constellation GNSS support, it ensures robust performance in challenging environments. The onboard XBee socket expands functionality with wireless modules, data loggers, and communication interfaces, making it a flexible choice for embedded navigation systems

This product requires a multi-band GNSS antenna (not included) for optimal performance. A standard GNSS antenna will not deliver accurate RTK results.
