List of compatible motherboards
Got it working with Fatal1ty AB350 Gaming-ITX/ac.
None of the connectors that it came with worked, so I had to re-pin the 2x7 2.0 ASRock connector that came in the kit. Using a razor blade I was able to life up the tabs on the connector and re-pin it to match the LPC connection on my board.
Color coated to match the wires, Red to any +3v and Black to any GND should work.
I can confirm that this works with the ASUS ROG STRIX X670E-A Gaming WiFi (LPC_DEBUG).
While they may be leaving out TPM headers, ASUS seems to still be putting undocumented 9-pin LPC_DEBUG headers on their motherboards.
I didn't see any mention of AMD 600-series boards in the first post (although I guess it hasn't been updated in quite a while).
