Lets say that I develop my highly complicated LED diode project on Raspberry Pi 3 B+ in Python. Now I don't want to use my RPi for this project becouse it is expensive and I want to move with next one, but I also want to have my diode thing work standalone.
Is there any cheaper, smaller etc platform where can I move directly my diode project to be standalone? I want to do this transfer with smallest financial and time cost and I don't want to use any C language microcontrollers etc, because I have done this on RPi.
Thank you for any suggestions.
