Postby jjnav » Sun Jun 24, 2012 11:28 pm

hello, im finishing my laser up, I have the diy retina board and can't find the pin to control laser power via pwm. Could any of you guys using retina help me out?
the board I have is a Rev 2.0 c2011 purchased two months ago with space for a sd card

thanks!
