C94-M8P - User GuideUBX-15031066 - R07 Early Production Information IntroductionPage 7 of 471 Introduction1.1 OverviewThe C94-M8P application board package provides the means for efficient integration and evaluation ofNEO-M8P, u-blox’s M8 high precision GNSS modules.The NEO-M8P module series introduces the concept of a “Rover” and a “Base Station”. By using a correctiondata stream from the Base Station, the Rover can output its relative position with stunning cm-level accuracy ingood environments.The C94-M8P board integrates the NEO-M8P-2 module with both Base Station and Rover functionality. TheC94-M8P includes a UHF radio link, allowing for easy setup and fast prototyping. The board also providesconnector pins, enabling a simple wired connection or communication alternatives using u-blox cellular andshort-range technologies.The C94-M8P application board package comes in four variants, each with an individually configured radio linkto meet different radio frequency requirements in different regions: C94-M8P-1-10/11 for China (433 MHz) C94-M8P-2-10/11 for USA and Canada (915 MHz) C94-M8P-3-10/11 or C94-M8P-3-10 for Europe (433 MHz) C94-M8P-4-10/11 for Japan (920 MHz)A label showing the application variant (ordering code) is located at the top-right corner of the board. Forinformation about variants with the old board version (C94-M8P-1-00, C94-M8P-2-00 and C94-M8P-3-00) referto Appendix E.3.1.2 C94-M8P packageThe C94-M8P package includes: 2 application boards (both with a NEO-M8P-2 module) 2 external UHF antennas 2 external active GNSS antennas 2 antenna ground planes 2 USB cablesA RF-shield is attached on the top of the radio modem.A plastic enclosure is attached on the top of the GNSS module. The purpose of the enclosure is to preventairflow affecting TCXO performance.1.3 Software requirementsTo comply with the instructions and examples in this document, the following software is required: The latest version of u-center for Windows (currently version 8.26).
