We asked Freescale because we could not find the information in the design pack for the TWR-K70F120M - "We are looking for the part number of plugs or headers like the ones we have with the TWRP-TOUCH-STR Kit for some preliminary software methods testing - We also did purchase some TWR-PROTO for use after what we would like to test on using the J3-J5 TWPRI TWR-K70F120M signals."
They responded -
J3 is from SAMTEC and part number is TFC-110-32-L-D-A-K.
J5 is also from SAMTEC and part number is TFC-110-02-L-D-A-K
We decided just to use TWR-PROTO cause we did not find the mating connectors real easy to get and the TWR-PROTO is nice.
