CAN Connector
This interface is compliant to CAN specifications rel. 2.0 part B. The transceiver used is designed for
high-speed (up to 1Mbps) CAN applications, and also offers improved EMC and ESD performances.
CAN Bus Connector is a 5-pin single line SMT connector, type MOLEX 53398-0571 or equivalent, with
pinout shown in the table on the left.
Mating connector: MOLEX 51021-0500 receptacle with MOLEX 50079-8000 female crimp terminals.
disconnected from the line by using JP2 jumper (Jumper inserted = termination connected).

Debug Uarts Connectors
Onboard, connectors CN11 and CN12 carry out signals of UART interfaces from the i.MX8X processor.
UART on CN11 is dedicated to debugging of Cortex-M4F processors. Connector is a 4-pin, type MOLEX
p/n 53398-0471 or equivalent, with pinout shown on the table to the left.
Mating connector: MOLEX 51021-0400 receptacle with MOLEX 50079-8000 female crimp terminals.
M4_UART_Rx: M4F debug UART port Receive signal, +3V3_RUN electrical level.
M4_UART_Tx: M4F debug UART port Transmit signal, +3V3_RUN electrical level.
UART on CN12 is dedicated to debugging of Cortex-A35 processors. Connector is same type as CN11, with pinout shown
on the table to the left.
UART2_Rx: A35 debug UART port Receive signal, +3V3_RUN electrical level
UART2_Tx: A35 debug UART port Transmit signal, +3V3_RUN electrical level
