A single person that has some good ideas every now and then...
An operating system that is written for the RP2040 and the RP2350 in MicroPython which gives similar functionality as some DOS and other CLI-based operating systems.
Includes some advanced functions, and networking capabilities, along with a modular hardware configuration that can be programmed to do essentially anything.
Currently working on v0.7-alpha. Adds a whole bunch of functionality and performance increases.
