Thanks for your reference article hope this TPM Module helps but as I am living in India its 8,732Rs. as of today I am checking with same other modules available if any.
Well, this is what can happen when you are looking for specialized hardware for a board from 2013; folks want compensation for having kept this (very low volume) item in their inventory for all this time. As you continue your search, be very careful to match the specification for the connector. The Technical Product Specification (TPS, available here) for the board contains a table detailing the necessary pinout.
Good luck in your search!
