I am looking for a 3.3 V power source in the Printrboard Rev. D pins.
I think there should be one somewhere... I do not know how to read the schematics that well.
Also, I am going to connect an HC-06, which draws 45 mA or less during operation. So, I need to know if it safe to get the power from the 3.3 V rail (if I find it).
So, the questions are:
- Which one is the 3.3 V pin?
- And how much current can I draw from it?
