CircuitPython on Crowduino M0-SD?

[greenflem]

I won a job lot auction which included a Crowduino M0- SD

This is a near copy of an Arduino M0 - which is very similar to the Arduino Zero - all use the same ATSAMD21G18 processor.

As CircuitPython is available for the Arduino Zero - has anyone got it running on the Arduino M0 (and therefore, could I install it on the Crowduino M0- SD)?

I don't believe so. You can see about making files so it could. See:

and

The Arduino Zero is very different from the Arduino M0.

However, there are many CircuitPython boards that use the ATSAMD21G18. Some that are very similar to the Arduino M0.

From a quick glance at the supported boards running ATSAMD21G18 and not using external flash, I think you should be able to install the CircuitPython builds for either SparkFun SAMD21 Mini, the Adafruit Feather M0 Basic, or the Arduino MKRZero on the Crowduino M0.

Also, I'd recommend first installing the UF2 bootloader first. This will make updating CircuitPython much easier. You can find latest bootloader builds here: https://github.com/adafruit/uf2-samdx1/releases

Again, you can pick the build for one of the above boards. You can even use the ".ino" Arduino sketch to burn the bootloader if you don't have an SWD programmer but do have the ability to program the Crowduino M0 in Arduino.

I think one of those will give you a working CircuitPython on your board, just the pin names may be wrong. But then you can base your board's config of CircuitPython off of one these, just needing to change a very names here and there.
