CAN interface signals
Two available CAN interfaces signals are directly managed by the i.MX 8M Plus processor.
CAN0_TX: CAN Transmit Output for CAN Bus Channel 0. +1.8V_RUN electrical voltage level signal with a 2k2
Ω
pull-up resistor
CAN0_RX: CAN Receive Input for CAN Bus Channel 0. +1.8V_RUN electrical voltage level signal with a 2k2
Ω
pull-up resistor
CAN1_TX: CAN Transmit Output for CAN Bus Channel 1. +1.8V_RUN electrical voltage level signal with a 2k2
Ω
pull-up resistor
CAN1_RX: CAN Receive Input for CAN Bus Channel 1. +1.8V_RUN electrical voltage level signal with a 2k2
Ω
pull-up resistor
Please consider that it is not possible to connect the SMARC CAN interface to any CAN Bus directly, it is necessary to integrate a CAN Bus Transceiver in the Carrier
board.
