Access REPL using serial terminal software
Upload scripts and libraries to the board's filesystem
Environment Setup
Install firmware on supported microcontroller
Connect board via USB
Ensure required libraries in lib/
Write main.py for application logic
Test peripherals and networking
Config Files
main.py - primary script
boot.py - initialization tasks
lib/ - peripheral libraries
data/ - persistent data files
assets/ - optional resources
