Tools
Things you run. The resources section is the link pile; this section is the workbench. A source-level Python debugger is planned and is not in this build — CPU-level debug already exists on some emulators.org machines.
Playground
Official firmware already running in the browser: Pico, Pico W, RP2350, ESP8266, C3, C6, Thumby, micro:bit.
Editor
Thonny, mpremote, VS Code, the micro:bit editor, and what we will host here.
Emulators
What a board emulator must model, and what we already have on emulators.org.
Interpreters
Exploded lexer, parser, bytecode and VM — the teaching path.
Embed kits
C, WASM, and host-language wrappers so MicroPython can script other programs.
