I have been using PyMCP2221A for a while now, and it has significantly simplified my MCP2221A integration projects. The library by nonNoise is incredibly well-documented and easy to incorporate, making my development process much more efficient. Highly recommend this to anyone looking for a reliable and user-friendly tool for MCP applications. Thank you, nonNoise, for this fantastic product!
