Frequently Asked Questions

These are some of the common questions regarding CircuitPython and CircuitPython microcontrollers.

I have to continue using CircuitPython 3.x or 2.x, where can I find compatible libraries?

We are no longer building or supporting the CircuitPython 2.x and 3.x library bundles. We highly encourage you to

update CircuitPython to the latest version (https://adafru.it/Em8) and use the current version of the

libraries (https://adafru.it/ENC). However, if for some reason you cannot update, you can find the last available 2.x

build here (https://adafru.it/FJA) and the last available 3.x build here (https://adafru.it/FJB).

Is ESP8266 or ESP32 supported in CircuitPython? Why not?

We are dropping ESP8266 support as of 4.x - For more information please read about it here!

As we continue to develop CircuitPython and create new releases, we will stop supporting older releases.

Visit https://circuitpython.org/downloads to download the latest version of CircuitPython for your board. You

must download the CircuitPython Library Bundle that matches your version of CircuitPython. Please update

CircuitPython and then visit https://circuitpython.org/libraries to download the latest Library Bundle.
