Digital Microphones
The expansion connector supports 3 additional default digital microphone inputs, support
maximum 6 DMICs:
DMIC_CLK1_LS2
DMIC_DATA1_LS2
DMIC_CLK1/DATA1_LS2 are multiplexing with on board MIC, see Section 3.18.3,
switch1 of DIP switch#16
DMIC_CLK2

4.2.4
CAN
The CAN signals are rounded from CAN transceiver which is from SPI translation. The
signals are:
CAN_H: CAN High-Level Voltage I/O
CAN_L: CAN Low-Level Voltage I/O
4.2.5
I2C
Two dedicated CCI (Camera Control Interface) I2C signal pairs are routed from QRB5165
SoC. 2.2k resistors are used in SOM to pull signals up for each of the I2C lines per the I2C
specifications. The signals are:
CCI_I2C_SDA2: Connects to CCI2 of QRB5165 SoC, Be configured to I2C SDA.
CCI_I2C_SCL2: Connects to CCI2 of QRB5165 SoC. Be configured to I2C SCL
CCI_I2C_SDA3: Connects to CCI3 of QRB5165 SoC, Be configured to I2C SDA.
