TW100PC Pin Map Overview

MCU Pin Map

The diagram below shows the MCU Pin Map of the TW100PC:

• Pins with labels → Reserved for internal use by the module (must be used in the base project)
• Pins with bold lines → Connected to the MiniPCI connector (for external expansion)

In short, you should always use the internally reserved pins for base projects, while MiniPCI pins can be utilized for additional features.

Internal Pin Configuration

The following diagram illustrates the internally assigned pins:

These pins are mandatory for the module’s operation, so it’s recommended not to modify them.

MiniPCI Pin Map

Here is the MiniPCI connector Pin Map, designed for external circuit expansion:

• Developers can connect custom external circuits through the MiniPCI pins.
• This provides great flexibility to adapt the TW100PC board to different application needs.

Conclusion

In this post, we reviewed the Pin Map structure of the TW100PC board.

The key takeaway is that internal pins are essential for stable operation, while MiniPCI pins offer expandability for project-specific applications.
