Review: Incredible Dev Board - Worked perfectly for reverting the fw on my ps4 fat. Fantastic teensy!
Review: It’s a good board, but not what I needed - This is a good board if it meets your needs. I had used a Teensy 2 before, so it seemed like a newer Teensy would be the way to go. I didn’t look closely enough to see that this board doesn’t support 5V inputs and that it isn’t well supported (if at all) for QMK firmware. Perhaps I will find a use for it in the future, though.
