You don't necessarily need a physical TPM module for Windows 11.

nein, dieses Modul passt nicht ! aber hier...https://www.ebay.de/itm/375784819204?chn=ps&_ul=DE&norover=1&mkevt=1&mkrid=707-166974-037691-2&mkcid=2&mkscid=101&itemid=375784819204&targetid=2274951440814&device=c&mktype=pla&googleloc=1004437&poi=&campaignid=21901617077&mkgroupid=169022828846&rlsatarget=pla-2274951440814&abcId=10095513&merchantid=5493928144&geoid=1004437&gad_source=5

Hello, the ASUS B550M-WiFi only has an empty pin socket, so the ASUS TPM-SPI (14-pin) must be purchased separately. The TPM-2.0 modules are relatively expensive > 30,00€ at GALAXUS ...via ebay you can get the TPM 2.0 from 9,00€ but the dealers are located in China...

According to the data collected, to be able to install Windows 11, you would need a TPM 2.0 compliant module for your motherboard, which is this one: ASUS Module TPM-M R2.0

Below is perhaps an alternative solution that doesn't cost money and where you don't have to wait for a delivery that might come sometime. - - - - - - - - - - - - - - - -- Currently there are very few mainboards or none that have a TPM 2.0 module permanently installed. Related to mainboards for self-build PCs. However, some offer the possibility of buying a TPM 2.0 module as a separate module and retrofitting it on the board in a slot provided for this purpose (https://de.wikipedia.org/wiki/Trusted_Platform_Module#/media/Datei:TPM_Asus.jpg). In addition to physical TPM modules, there are also fTPM (firmware TPM, called PTT at Intel). Intel and AMD have been integrating TPM version 2.0 into their CPUs for several years. To be able to use this, the BIOS of the PC/notebook must support it and it must also be activated there. Intel CPUs from the 8th generation onwards usually have TPM integrated. Intel calls this PTT (Platform Trust Technology). AMD has integrated TPM as fTPM in the CPUs since the use of Socket AM4 from around 2016.

This should actually already have a TPM module installed, activate it under BIOS -> Security -> Security Device Support (Enable). Then reboot and open Windows with the command "Windows key" + "R" in the field "tpm.msc". The information on the TPM module should then be there.

No, but this one: ASUS TPM-M R2.0 Module The mainboard manual has the pinout on page 43. The module is intended for MBs that communicate with the module via SPI. But the MB you linked wants a TPM with LPC interface. The ASUS TPM-M R2.0 fits in this case. (You can't really see it on the Digitec picture, but on the manufacturer's page it says with the LPC, just like in the instructions for the mainboard). Hope this doesn't come too late :).
