R russbow Senior Member May 6, 2013 #1 Is there any problem connecting an axe 133y OLED display to the serial board if the board already has the contrast variable resistor installed? I am swapping out the old LCD for a new OLED. Just wondered if there are any Gotcha's

N nick12ab Senior Member May 6, 2013 #2 Could be - the contrast pin on the OLED has a trace that goes somewhere into the middle of the circuit. Simply omit the connection between the AXE133 PCB and the OLED display for the contrast pin to avoid any problems.

R russbow Senior Member May 6, 2013 #3 Thanks Nick. Re-loaded the the 18m2 firmware and all ok. Interesting thought though. Technical ?
hippy Technical Support Staff member May 6, 2013 #4 The contrast pot goes direct to the LCD/OLED display and on the OLED that signal pin is not connected.
