AJMRTC RS485 CAN Expansion Board for Jetson Nano, Digital Isolation Design, Onboard TVS Diode, Built-in ESD Surge Protection Circuit, 40PIN GPIO Header for Industrial Modbus CAN2.0A/B Automation Senso

AJMRTC RS485 CAN expansion board is designed exclusively for Jetson Nano. It integrates RS485 and CAN bus transceivers together with digital isolation chips to separate the signal side and bus side. The onboard TVS provides reliable protection against electrostatic discharge and voltage surges which are common in industrial environments. It uses SPI for CAN communication and UART for RS485, compatible with mainstream open-source drivers and Python sample codes. It works well for industrial sensors, PLC connection, robot control, field data acquisition and long-distance bus communication projects.
