Adafruit Blinka

  • Software
  • Microcontrollers and firmware tools
  • Library

A library that emulates the CircuitPython API so code written for CircuitPython can run on CPython or MicroPython hosts such as Raspberry Pi boards.

Made by Adafruit Industries, United States (checked on github.com/adafruit (opens in a new tab)).

What it does

  • Provides CircuitPython-style modules such as digitalio, analogio, busio, pwmio, and keypad on host computers.
  • Offers a board module with breakout-specific pin names so example code can address pins by label.
  • Includes software and hardware I2C and SPI interfaces, plus UART support through busio.
  • On Raspberry Pi, digital GPIO uses the gpiod bindings and PWM uses separate Adafruit PWM backends.
  • Software PWM accepts 1 to 10000 Hz, with timing and jitter depending on Linux scheduling.
  • Installable from PyPI with pip, including into a virtual environment.
