Coconix uses the BSD 3-clause license and contains large portions of code originating from KernelUNO.
Some may notice that the ArduinOS and KernelESP projects have many of the same commands as Coconix.
ArduinOS and KernelESP are rewrites of the KernelUNO codebase with features adopted from then-unmerged pull requests, and they are not affiliated with the Coconix project in any way. In addition, all versions of the ArduinOS project predating 72062e7 contain portions of code derived from the copyrighted work of the authors of Coconix and KernelUNO, and which have an unclear copyright status.
