라즈베리 파이용 RS485 CAN HAT 보드
(RS485 CAN HAT for Raspberry Pi)
개요
- 본 제품은 라즈베리 파이와 사용이 가능한 RS485 CAN HAT 보드입니다.
- 라즈베리 파이를 RS485 혹은 CAN 통신을 하게 할 수 있습니다.
- 동작 전압은 3.3V입니다.
특징
- Standard Raspberry Pi 40PIN GPIO extension header, supports Raspberry Pi series boards
- CAN function, onboard CAN controller MCP2515 via SPI interface, onboard transceiver SN65HVD230
- RS485 function, controlled via UART, half-duplex communication, supports automatic TX/RX control without programming, onboard transceiver SP3485
- Onboard TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit for RS485 transceiving, lightning-proof & anti-electrostatic
- Reserved control pins, allows to work with other control boards
- Comes with development resources and manual (examples in wiringPi/python)
