Can; I2C; Gpios - Thundercomm TurboX C865 Dev Kit Hardware User's Manual


DMIC_CLK3

DMIC_DATA3

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 SM8250 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 SM8250 SoC, Be configured to I2C SDA.

CCI_I2C_SCL2: Connects to CCI2 of SM8250 SoC. Be configured to I2C SCL

CCI_I2C_SDA3: Connects to CCI3 of SM8250 SoC, Be configured to I2C SDA.

CCI_I2C_SCL3: Connects to CCI3 of SM8250 SoC. Be configured to I2C SCL

4.2.6 GPIOs

C865 DEV KIT implements more GPIOs for low-speed expansion connector. The GPIOs are 1.8V
voltage rail.

GPIO-M/QUP-B0: Connects to GPIO_125 of SM8250.

GPIO-N/QUP-B1: Connects to GPIO_126 of SM8250.

GPIO-O/QUP-B2: Connects to GPIO_127 of SM8250.

GPIO-P/QUP-B3: Connects to GPIO_128 of SM8250.

GPIO-Q/I2S1_WS_LS2: Connects to GPIO_147 of SM8250. Can be configured as I2S WS
