CircuitPython Turbo Makes Your Hot Loop 20 to 70 Times Faster Without Leaving Python
CircuitPython Turbo, from Adafruit's Mikey Sklar, pairs a 2–3KB native-code loader (now importable on RP2xxx boards as of CircuitPython 10.3.1) with a host CLI that compiles marked functions via mpy-cross. On twelve boards, viper-compiled inner loops ran 19x to 72x faster than bytecode.
