Questions tagged [adafruit-circuitpython]

Use of the CircuitPython language and libraries on supported hardware, not just Adafruit boards and devices.

CircuitPython is derived from MicroPython through the support of Adafruit to simplify the low-level access to many standalone microcontrollers by programming in Python directly on the device, without the need for an IDE. Extensive libraries allow for the easy use of add-on devices from several manufacturers.
