Since Windows 11 announced its demand for TPM module, the price of PC motherboard TPM add-on board, which was previously abundant and not paid enough attention, has soared. We have got chips and soldered them to our own circuit board, and the [Viktor] project is another example. [Viktor] checked the online market list of TPM module of its Gigabyte aorus gaming 3 motherboard and found that its starting price is about 150 euros, which is almost the same as the price of the motherboard itself. Therefore, as a self respecting hacker, he chose the DIY way and went well.
According to the schematic diagram in the data sheet, he quickly made a simple kicad layout, matched it with the pins in the motherboard user’s manual, and then ordered the motherboard and slb9665 chip from pcbway and eBay. When they arrived, [Viktor] assembled the circuit board and found a small mistake – he designed a module for 2.54mm pin heads, but his motherboard had 2.0mm pin heads. He wired a small adapter to make it an assembled v1. 0 motherboards work normally, and there are no TPM complaints when installing windows 11. He showed that he designed a new v1. 1 version with updated connector and released its (untested but should be usable) design file for us on GitHub. These modules may vary by manufacturer and motherboard series, but with the release of each module, a group of hackers can save money and get a weekend project that can almost guarantee normal work.
Whether the goal of running Windows 11 is ultimately worth it or not, it has been achieved. Since scalpers are robbing people who only want to use hardware on the new operating system, rolling their own TPM PCB is a very attractive solution! Last time we discussed the DIY TPM module of ASRock server motherboard, we had a lively discussion in the comments. If you want to create your own TPM board, you may do worse than checking their suggestions and opinions!
