Features at a glance
The RS232 RS485 CAN Board is an industrial isolated interface expansion board designed for Raspberry Pi 4B / Raspberry Pi 5, provides a variety of industrial communication interfaces: 2x RS485, 1x RS232, 1x CAN FD, and 1x CAN, each with electrical isolation. Onboard lightningproof, anti-electrostatic protection, etc. for more secure and reliable communication.
Comes with industrial rail-mount enclosure for easy integration in industrial control applications. Provides sufficient internal space for users to stack other HATs or expansion boards, and reserved installation space of PCIe adapter board for Raspberry Pi 5, which is more convenient for further expansion.
- Based on Raspberry Pi 40PIN GPIO header, suitable for Raspberry Pi 4B and Raspberry Pi 5
- Adopts SC16IS752 and SP485 combination scheme, expands SPI to 2x RS485 interface
- Adopts MCP2515 and SN65HVD230 combination scheme, expands SPI to 1x CAN interface
