Hello, I am just about to order an expansion board for my IGEPv2 RC board and was wondering if the back-light brightness of an LCD display attached to the expansion board can be controlled from the main board. I am asking because I noticed that the expansion board has 2 additional pins on connector JA42, and one of those pins (pin 21 - LCD_PWMBKL) appears to be the PWM signal to regulate the back-light brightness. Pin 21 and pin 22 however do not mate with the 20 pin connector on the main board. Is there a different way of controlling the back-light brightness? Cheers, Holger

    The IGEP v2 RB and RC don\\\'t have support to control the backlight brightness, this only will be available in future versions.
