Tpm board
About the Tpm board
Tpm board is an open source PCB design by avivgr, published on GitHub. It is a 2-layer board measuring 25 × 25 mm, with 6 components from 5 distinct parts.
Other key parts include the SLB9670VQ20FW785XUMA1. By type, the board carries 3 capacitors, 1 IC, 1 connector and 1 resistor.
From the project
A PCB for OPTIGA™ SLB 9670 TPM2.0
This is a KiCad project for a simple breakout PCB around the OPTIGA™ SLB 9670 TPM2.0 chip. The OPTIGA™ SLB 9670 TPM2.0 uses the SPI serial interface to a host. You can connect this board to a PC motherboard (using jumper wires), or to an SBC like the raspberry pi (more details below).
Because there is a price hike on TPM2.0 boards due to Windows 11 requirements. Also, this is a great learning tool for TPM2.0 technology, instead of using a software emulated TPM.

Tpm board: common questions
How big is the Tpm board?
The Tpm board measures 25 × 25 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Tpm board?
6 components, from 5 distinct parts. The full bill of materials is listed on this page.
Where can I download the Tpm board design files?
From the avivgr/tpm_board repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Tpm board design in my own project?
The repository has no license, so all rights stay with avivgr. Use it as a reference, and ask the author before reusing the design.
