Digital signal indicator on some pins, question

Folks,

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?

Thanks.

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: https://docs.particle.io/reference/firmware/photon/#analogwrite-pwm- :slight_smile:

Nice! thanks a lot.
