GC-TPM2.0_S – 12-1 Pin SPI TPM 2.0 Module – Discrete Hardware Security

GC-TPM2.0_S – 12-1 Pin SPI TPM 2.0 Module – Discrete Hardware Security

A compact TPM 2.0 add-in card for motherboards that use the 12-1 pin SPI_TPM header. Provides hardware root-of-trust for BitLocker, measured boot, and platform attestation.

Description

This module plugs directly into a board’s SPI_TPM (12-1 pin) header and exposes a TPM 2.0 device to firmware and the OS. Ideal for enabling Windows and enterprise features that require a discrete TPM on systems without fTPM/PTT or when a removable module is preferred.

Technical Specifications

☑️ Key Features

• ☑️ Hardware root-of-trust for encryption keys and credentials
• ☑️ Direct 12-1 pin SPI_TPM plug-in—no cables required
• ☑️ TPM 2.0 support for BitLocker, Device Encryption, Secure Boot workflows
• ☑️ Low-power, compact module for desktops and workstations

⚙️ Fit Notes

• Header type matters: This is SPI_TPM (12-1 pin). It is not the 14-1 LPC style or 20-pin server-style TPM. Check your board’s silkscreen and header layout before ordering.
• Pin-1 orientation: Align the keyed pin correctly; never force insertion.
• BIOS/UEFI: Enable Discrete TPM (disable fTPM/PTT if your board requires choosing one).
• Re-use/migration: If moving the module to another system, clear/initialize the TPM in firmware before enabling BitLocker or similar features.
