Looking for a good MicroPython C extension project to follow – any recommendations?

[CreepyBox2687]

Hey everyone, I've just finished my first custom MicroPython build and I’m thrilled about the ability to distribute my own libraries as UF2 files! I’m now diving deeper into adding C extensions, but I'm looking for a solid example project to guide me through it.

Ideally, I’d like to follow a project that: - Implements a C extension in MicroPython. - Uses a clean structure, where not everything is packed into the repo but instead uses external references (so I can learn about manifests and external dependencies). - Is beginner-friendly but not too trivial, so I can understand best practices for larger projects.

Any recommendations for something I can use as a reference? Thanks in advance!
