SPECIFICATIONS

Standard Raspberry Pi 40PIN GPIO extension header, supports Raspberry Pi series boards

Adopts SC16IS752+SP3485 dual chip combination, converts SPI to RS485, data rate up to 921600bps

Allows transceiving data manually or automatically, configured by DIP switch

Onboard TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, lightning-proof & anti-electrostatic

Onboard auto-recovery fuse and protection diodes, ensures the current/voltage stable outputs, provides over-current/over-voltage proof, improves shock resistance

Onboard LEDs for indicating the power and transceiver status

Breakout SPI control pins, for connecting with host control boards like Arduino

Comes with development resources and manual (examples in C and Python)

The RS485 CAN HAT will enables your Pi to communicate with other devices stably in long-distance via RS485/CAN functions.

Features:

• Raspberry Pi connectivity, compatible with Raspberry Pi Zero/Zero W/Zero WH/2B/3B/3B+

• 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)
