I saw immediately that it has a Pro Micro -compatible pinout.
Indeed, the Pro Micro pinout has become a de-facto standard for DIY keyboards.

Sparkfun already has a Pro Micro RP2040 with similar features (USB-C + breakout, compatible I²C port, castellated edges, ...) but with twice the flash for a dollar more.

Some newer Pro Micro-compatible boards for the DIY keyboard community have five additional GPIO pins on the short edge. Too bad that neither of these two do.
