I was reading the Photon documentation and when I looked at the DAC in closer detail I found something that didn’t agree.

It is on this page:  
[http://docs.particle.io/photon/photon-datasheet/](http://docs.particle.io/photon/photon-datasheet/)

The issue is the second DAC. One says pin A5, the other pin A3.

It’s definitely a documentation error - A3 is correct. Thanks for pointing this out! 👍
