RTMI Connector
The real-time monitoring interface connector is used to connect to Trinamic’s RTMI adapter for live
monitoring and tuning of the TMC4671 control loops at control loop sampling frequency.
The onboard connector itself is of type Hirose DF20F-10DP-1V(56).
The mating female counter part is of type Hirose DF20A-10DS-1C. A connecting cable comes with the
USB-2-RTMI adapter.
