Digital signal indicator on some pins, question


I found this Photon pins layout, my question is regarding the pins that have the digital signal indicator. I thought the photon can handle any digital signal on any pin, am I right? Its just a matter on configuration, right?


That’s not a digital signal indicator, that symbol means PWM (pulse width modulation). And yes, all the “A” pins, “D” pins and “RX” and “DX” are digital I/O capable.

Aaah! ok

Another question: What is the modulation frequency for these pins? can the frequency be changed?

Official docs always help: :slight_smile:

Nice! thanks a lot.
