X2 destroyed, other PWM pins?

Post by rankor » Tue Jun 23, 2015 11:23 pm

Seems like I destroyed the X2 pin when I unsoldered some header pins. Is there another pin that can be used instead for PWM?

If you look at http://docs.micropython.org/en/latest/quickref.html all if the pins tagged with a purple background TIMx/CHy support PWM.

Just by curiosity, how do you know that the X2 pins is destroyed?
I ask because after soldering come male headers, some of my pins do not work any more or have a strange behaviour and I though that maybe the soldering material was too much and it connected different pins, but until now I do not see any connection between the pins. So I assume maybe an overheat of an amount of time of the pins could lead to destroying a pin? What is your opinion about this?
Thank you.

Well, unsoldering is kind of risky. The board itself has several layers and it is easy to damage the actual contact area with the (header) pins that will go through the whole.

I consider it damaged because I soldered it well and there is contact between the board and the external device so the soldering os not bad and I use the pin exactly as another pin and the other pin works and X2 does not.

Ok Thank you for your answer.
So any recommendations for soldering headers in the board?
