SBC-C31 offers, a dedicated embedded Display Port interface.
For the connection of this kind of displays, on-board
®
there is a VESA
certified connectors for embedded
Display Port interface, type STARCONN p/n 300E40-
0110RA-G3
or
equivalent
(microcoaxial
connector, 0.5mm pitch, 40 positions).
eDP_LCD_PWR can be factory regulated to be connected to +5V_ALW or +3.3V_ALW, while
eDP_BKLT_PWR can be factory regulated to be connected to +5V_ALW or +12V_ALW.
These are factory configurations, please take care of specifying which is the configuration
needed for eDP_LCD_PWR and eDP_BKLT_PWR voltage rail.
Here following the signals involved in eDP management:
eDP_ML0P/eDP_ML0N: embedded DP differential data pair #0.
eDP_ML3P/eDP_ML1N: embedded DP differential data pair #1.
eDP_ML3P/eDP_ML2N: embedded DP differential data pair #2.
eDP_ML3P/eDP_ML3N: embedded DP differential data pair #3.
eDP_AUX_P/eDP_AUX_N: embedded DP auxiliary channel differential data pair.
eDP_BKLT_EN: eDP_LCD_PWR electrical level Output with a 1kΩ pull-up resistor, Backlight
Enable signal. It can be used to turn On/Off the backlight's lamps of connected displays.
eDP_BKLT_PWM: this signal can be used to adjust the backlight brightness in displays
supporting Pulse Width Modulated (PWM) regulations (eDP_LCD_PWR electrical level).
