Isolated RS485 CAN HAT for Raspberry Pi Ardui STM32 2-Ch CAN Bus+1-Ch RS485 Adopts MCP2515 + SN65HVD230 Dual Chips Slide Switch 3.3V 5V Level Multiple Protection Circuits

Overview: This RS485-Dual-CAN-I module for Raspberry Pi adopts expansion circuit 2 CAN and 1 RS485 interface, and supports user-defined baud rate communication; onboard digital isolation chip and integrated isolation power supply can offer stable isolation signal and voltage, and the isolation terminal does not need additional power supply, having TVS protection, low power consumption, high reliability and strong anti-interference. The isolated RS485 CAN expansion board for Raspberry Pi also provides a DC power input interface circuit, which can provide power for the module and for Raspberry Pi simultaneously. We also provide demo codes for Raspberry Pi .

• MCP2515+SN65HVD230DR dual chips. This isolated RS485 can hat uses CAN controller MCP2515 and CAN transceiver SN65HVD230DR dual-chip combination scheme for Raspberry Pi Zero Zero W Zero 2W 3 3B 4B, allowing 2 channels CAN interface communication, and only needed one module can be used for CAN transceiver test for Raspberry Pi, onboard 1 channel RS485
• Onboard power conversion circuit. The RS485 can bus supports a wide range of DC voltage power supply from 7 to 28V, and can supply power to the Raspberry Pi motherboard at the same time
• Onboard 2 slide switches. The RS485 2-ch can hat is onboard slide switch that is convenient to be changed the signal working level of 3.3V or 5V for the module. Each interface is equipped with a 120Ω terminal resistor, which also can be set and enabled through the slide switch
• Multiple protection circuits. The RS485 dual can expander board is on-board digital isolation chip, making signal isolation communication safer, more stable, and stronger in anti-interference; onboard SM24CANB (transient voltage suppression tube), anti-static and transient peak voltage
• Convenient for using: On-board pin header and terminal 2 wiring methods, more convenient wiring. Independently lead out the SPI control interface, which is easy for connecting to main control boards such as STM32 and Ardui
