This is a keyboard firmware similar to QMK, but targeting 8051-based devices like the Sinowealth SH68F90A (labeled as BYK916 or BYK901). It's aimed to be at least partially compatible with QMK configurations.
The S (Small) in SMK comes from this firmware using SDCC to build itself.
This firmware is still highly experimental, so be cautious when trying to use it or extend it.
You can very easily end up with a bricked device if the written firmware can't jump back into ISP mode, so before testing or modifying it, it's best to have a full dump of your stock firmware and a tool (like the Sinolink) that can write it back.
