TPM/LPC Header/Cable pinouts

Pinouts are available here: http://elmorlabs.com/index.php/2018-09-23/p80db1l-port-80-lpc-debug-card/

Note that some Asus boards have a smaller LPC only version of their TPM header which has the same number of pins, pin pitch and keying as their SPI header (2x5 2.0mm, pin#10 key). The SPI header is usually close to the on-board BIOS chip and the LPC header usually near the bottom edge below the last PCI-E slot. Additionally SPI TPM headers are not compatible with the debug card.

Do those pinouts apply for the new version P80DB2 LPC Debug Card, too?

On the motherboard side, yes. The pinout of the debug card itself is different.
