-  <description>Model of the NXP HoverGames Drone development kit (KIT-HGDRONEK66). The PX4 software compatible kit provides mechanical, RC remote and other components needed to evaluate the RDDRONE-FMUK66 reference design. The FMU includes 100Base-T1 Automotive Ethernet, dual CAN transceivers, as well as SE050 secure element, and works with add on boards NavQPlus, MR-T1ETH8, MR-T1ADAPT, and CAN-nodes such as UCANS32K1SIC.  Kit may be used with, and contains the components needed for the HoverGames.com coding challenges.</description>
