|

|

- Supports native USB on all boards, allowing file editing without special tools.
|
||||
- Supports only SAMD21, SAMD51, nRF52840, CXD56, STM32F4 and i.MX RT ports.
|
||||
- Tracks MicroPython's releases (not master).
|
||||
- Floats (aka decimals) are enabled for all builds.
|

- Error messages are translated into 10+ languages.
|
||||
- Does not support concurrency within Python (including interrupts and threading). Some concurrency
