CircuitPython 在去年与 Pico 一起发布，虽然它与MicroPython 有些相似，但也有一些区别。 如果需要使用中断和线程等高级功能，或者需要在 Python 中完全访问 RP2040 的可编程 I/O（PIO），一般需要使用 MicroPython。

CircuitPython源于MicroPython，被Adafruit支持，目前已经有100多种板子支持CircuitPython，有近一半的板子都是Adafruit的，因为Adafruit是做各种板子的大户人家。 下面就发几块板子看看。

The chip inside is an Atmel SAMD21E18A-U, and is apparently running Adafruit’s CircuitPython platform. This discovery led to further digging, of course.

Priced at just $4, the Raspberry Pi Pico is built on RP2040 chip. “This is the first beta release of CircuitPython 6.2.0.

CircuitPython 8.0.0-rc.1 is now available via the official GitHub release page by following the link below and brings with it a wealth of functionality.

CircuitPython reached a major milestone last week as it welcomed its 100th board into the fold: the wristwatch form factored badge designed for the 10th annual Open Source Hardware Summit, which ...

The Raspberry Pi Foundation is finally designing a microcontroller with its own chip. Here's how you can use it for your projects and everything you need to know about its features and specs.
