Can i Use any usb to serial adapter to flash the lumazoid?
I need to put some more colorschemes on it and less patterns for a project using 4 lumazoid boards.
Yes, but the very cheap versions of usb-serial adapters have all kinds of problems. I personally use only adapters that I know have genuine FTDI chips on them. I resell the Adafruit FTDI Friend adapter. More expensive, but no problems, either.
