Hello, is it possible to control backlight on the NHD-2.8-CSXP-BREAKOUT breakout boards?

The breakout has BLK pin which is connected to what seems to be a regulator for backlight but feeding it with PWM does not seem to have any effect and the pin is marked as "No Connect" in the product specifications PDF.

Thank you,

Adam

  Hi Adam,

  Unfortunately, with the current design, it is not possible to control the backlight on the NHD-2.8-CSXP-BREAKOUT display module.
