    Correct Teensy Board for simple Midi project

    Hello,
    I have recently completed a proto type of a project using a teensy 4.0 board. The purpose of the project is to allow me to take a midi signal from a computer and turn on a light.
    The Teensy 4.0 board worked perfectly for this. However I need to make several more and in the interest of keeping costs as low as possible I wondered if I really needed a 4.0
    I have a concern that I'm swatting a mosquito with a canon since all I'm doing is turning a pin on when I see a note go on, and visa versa.
    Anyone have an experience with one of the lower cost Teensy boards for a midi interface?
    Thanks
    -Nathan

    You can compile your code by selecting the LC in the IDE and see whether RAM and Flash is sufficient.
    Performance-wise, the LC should indeed be OK for your purpose as you describe it.

    My code used less than a percent of the 4.0 so it sounds like you have both answered my question, thank you very much I didn't feel confident just assuming I'd be OK with that board.

    surely it have enough memory for that application
    even a pic18f4550 have 32KB flash and 2KB ram
    and that worked super as a midi2uart
    until I did buy a teensy 4 that could also have the synth part
