Hi there!

For quicker and more in-depth technical & after-sales support, we suggest contacting us directly via email at support@geekworm.com.

To help us assist you promptly, please include in your email:

• Your order number and the platform where you purchased it.

• Your device specs (model, OS, etc.).

• The setup/configuration you're attempting, along with your installation and connection details.

• Specifics about the issue you're facing—photos or videos are extremely helpful!

Please note that as a highly DIY product, its performance can be influenced by many factors (serial port encoding being just one example). The issue may not be with the board itself. Without sufficient details, it's too early to conclude they're "dead boards."

Send us an email, and our team will provide you with thorough technical support. Even if it turns out to be a product quality issue, we have a solid after-sales solution—so please don't worry!
