Breakout Pins
Note:
All the trigger, serial control, and button pins operate with
3.3V
logic. Do not provide 5V to any of these
pins; it will permanently damage the board. The exception to this are the MIDI pins, which are opto-isolated.
There are a lot of breakout pins on the Qwiic Tsunami. While we won't cover them all, we'll discuss the pins with
major functionality that users would normally interface with.
