Hi all,
I have a small test setup with a Teensy 3.2, and audio board, and an HT16K33 based LED matrix. Everything is connected via I2C, and it works great. I just realized that the matrix is powered off of 5V, which should mean that it's putting 5V down SDA when I read back info from the chip.
As I said, everything currently works fine. Should I be concerned about that 5V? The Teensy should be fine, but the datasheet on the SGTL5000 says I'm out of spec.
Thank you!
