Hi, I'm a little confuse with the information about wich are the pins that contains pwm feature, the official data says that D4,D5,D6,D9,D10,D11,D12,D13 (8 pins )contains pwm; datasheet of arduino micro include D3 and exclude D4(see atached file); and information from internet says that D3,D5,D6,D9,D10,D11,D13(7 pins), what is the correct information? thanks in advance.

The pin numbers in the datasheet are not the same pin numbers as on the board; there is a mapping that maps processor pins to Arduino pins.
Follow the schematic / official data for the board, not the datasheet.
Hi sterretje, thanks for your answer, my mistike, when I said datasheet I really want to say schematics, and watching that file I found that confusing information.
Any pin with OC in the name (inside the IC outline) is a PWM pin (to my knowledge).
You can easily test them all with a led and resistor; pin 13 already has the onboard led.
Yes I will need to test it, I would like to avoid that test and focus on my project but I have to do it. Just for clearfy things, in schematics PWM pins are labeled with a green text, those are:
A) IO11*
B) IO10*
C) IO9*
D) IO13*
E) D5*
F) D6*
G) IO12*
H) D3/SCL* (ERROR IN 34 PINS HEADER, SAYS WITHOUT * SYMBOL)
that correspond to a pin Arduino Mcro as follows:
A)~D11
B)~D10
C)D9
D)~D13
E)~D5
F)~D6
G)~D12
H) ¿ D3 ?
