  • 2 external active GNSS antennas
  • 2 micro‑USB cables


Product Description

   The C94-M8P application board allows efficient integration and evaluation of NEO-M8P, u-blox’s M8 high precision positioning module. The NEO-M8P module series introduces the concept of a “Rover” and a “Base Station”, bringing RTK technology to u-blox’s product portfolio. By using a data stream from the base station, the rover can output its relative position with stunning cm-level accuracy in clear sky environments.

   The C94-M8P application board integrates NEO-M8P-2 module with both base station and rover functionality. The C94-M8P includes a UHF radio link, allowing for easy setup and fast prototyping. The board also provides connector pins for u-blox C027 and other application boards, enabling communication alternatives using u-blox cellular and short-range technologies.
