It's easy to use the 12mm LED pixels with CircuitPython and the Adafruit CircuitPython WS2801 module. This module allows you to easily write Python code to control the lights.
You can use these LEDs with any CircuitPython microcontroller board or with a computer that has GPIO.
CircuitPython Wiring
You can wire up the WS2801 strand for CircuitPython and using any two GPIO pins. One will serve as the clock Pin and one as the Data Pin.
Although the driver is capable of using Hardware SPI, we recommend not using it because the timing can vary from microcontroller to microcontroller and isn't reliable on certain boards.

Hardware SPI Wiring on the Raspberry Pi
The Raspberry Pi seem to be an exception in that Hardware SPI seems to work pretty well on here.
