HDMI, LVDS, and MIPI displays

The ConnectCore 8M Mini System-on-Module supports only one MIPI-DSI display interface. On the
ConnectCore 8M Mini Development Board, this MIPI-DSI display is managed so that three different
display interfaces are supported, although only one of them can work at a time.
HDMI: The Lontium LT8912B bridge is populated on the development board to adapt the MIPI-
n
DSI interface to HDMI. This HDMI interface is available over a standard HDMI connector.
LVDS: The SN65DSI83 bridge is also populated on the development board to adapt the MIPI-DSI
n
interface to LVDS. This LVDS is available over a 20-pin connector (J32), also supporting
backlight control and I2C touch controller:
