“Great Product. Perfect for some audio tinkering. However, doesn't have build in DAC like earlier Teensy models. You'll need the audio shield for that.”
“I'm a fan of the Teensy and bought a pair of 4.0s because it seemed rude not to at the price. I'm only using them to read CAN messages at the moment for which the 3.2 would be plenty good enough. Everything seems compatible and they are outrageously fast. Perhaps I will use some more of the power later.”
