If you are using a TM3 modules with the letter "K" at the end that means that the module requires a HE10 connector.
So have the following references for HE10 connector with flying leads:
• TWDFCW30K (3m length)
• TWDFCW50K (5m length)
If you are using:
• TM3DI16K or TM3DQ16TK you will need one (1) of the TWDFCW*0K cables connector.
• TM3DI32K or TM3DQ32TK you will need two (2) of the TWDFCW*0K cables connector.
