    Often when you get an SD error message, it just means you need to replace your microSD card and burn a fresh copy of the data on there. You can always download the data from GitHub here:


    However, sometimes the SD reader itself stops working. Until now, we’ve needed to replace the entire LED board to solve this problem. The problem is, I’m all out of boards. So I ported the code to Teensy 3.5. It’s not an ideal solution, but it’s a good one. The Teensy 3.5 has a built-in micro SD reader, and a much faster one at that.

    The most important thing to remember is you MUST LINE UP THE PINS CORRECTLY. If you look at the black PCB on the rear of Game Frame, you’ll see the word USB underneath where the USB jack is on the little green Teensy LC. Remove the Teensy LC and place the Teensy 3.5 in the same orientation. It’s a longer board, so some pins won’t make contact, but you don’t need those extra pins.
