TX-MIPI-LVDS Mainboard

This is our hardware documentation for the TX-MIPI-LVDS Mainboard, usually coming with the TX8M Linux Development Kit.

There are several pin headers to connect to GPIO, I2C, SPI, SD-card, UART or JTAG signals.

Note

There is a little triangle symbol printed for each connector, that marks PIN 1 of a connector. The connectors have different orientations.
