The actual hardware used in this hands-on demonstration features the W55RP20 as the main controller chip. The circuit logic and UF2 flashing operation principles are universally applicable, with only the main controller model differing. The original chip model mentioned in the circuit descriptions below is provided for reference purposes only. Implementation of block‑device abstract base class As introduced earlier, MicroPython does not provide ready‑to‑use block‑device functions, but it supplies…
