4.8 Legacy Audio/JAMR3 Connectors

There are 3 B-B expansion connectors available on infotainment board to interface legacy audio/JAMR3 expansion board.

8 McASP data signals, frame sync and clock signals from the connector is directly connected to INFO-CP B-B expansion connector. WKUP_I2C0 & I2C3 signals from Infotainment board connected to the connector for accessing the board ID information and configuration. The device reset is controlled by the I2C GPIO expander on Infotainment Board.

The 12 V power supply is available from infotainment board for powering the expansion board. VCC_3V3 Supply is connected to the expansion connector to enable regulators on the expansion board.
