After an extensive development process which involved numerous design iterations and reconsideration of implementation methods, the updated project version that encompasses all concept ideas has been released!

Compared to the previous version, the PCBA is more:

It has now evolved from being just another driver to becoming a powerful tool for education, development, testing, and system modeling.

Does it work? The short answer is yes. However, diving deeper, things get a bit more complicated.

From a hardware perspective, there are a few minor issues, which fortunately don't have an impact on the primary functionality. These known issues include:

Apart from these, all other driver functions operate correctly.

On the code side of things, it's a different story. A vast amount of work is still needed to release the complete driver control library that would unlock its full potential. But there's hope that it's just a matter of time.
