SeenGreat Isolated RS485 CAN HAT for Raspberry Pi Series 2-Ch CAN+1-Ch RS485 Adopts MCP2515 + SN65HVD230 Dual Chips Multiple Protection Circuits SPI Interface Slide Switch for 3.3V/5V Level

Produktbeschreibung

Dual Chips: The RS485 can hat for Raspberry Pi Zero/Zero W/Zero 2W/3/3B/4B adopts CAN controller MCP2515 and CAN transceiver SN65HVD230DR dual-chip combination scheme, supportting 2 channels CAN interface communication, and only one module can be used for CAN transceiver test on Raspberry Pi, meanwhile onboard 1 channel RS485 Slide Switch: This RS485 2-ch can expansion board is onboard slide switch which can be switched the signal working level of 3.3V/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 hat 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 The RS485 can bus onboard power conversion circuit 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 Easy to Use: On-board pin header and terminal two wiring methods, more convenient wiring. Independently lead out the SPI control interface, which is convenient for connecting to main control boards such as STM32/Ardui
