RS485 CAN HAT for , Allows Stable Long-distance CommunicationThe RS485 CAN HAT will enables your Pi to communicate with other devices stably in long-distance via RS485/CAN functions.1. Standard 40PIN GPIO extension header, supports series boards2. CAN function, onboard CAN controller MCP2515 via SPI interface, onboard transceiver SN65HVD2303. RS485 function, controlled via UART, half-duplex communication, supports automatic TX/RX control without programming, onboard transceiver SP34851. Onboard TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit for RS485 transceiving, -proof & anti-electrostatic2.
