2 Channel Isolated RS485 Expansion LINE
2 Channel Isolated RS485 Expansion LINE for Raspberry Pi2-channel isolated RS485 expansion HAT designed for Raspberry Pi adopts SC16IS752 + SP3485 solution with embedded protection circuits such as power supply isolation, ADI magnetic isolation and TVS diode.
Easy to control 2-channel RS485 for auto transceiver via SPI interface. Due to its fast communication, stability, reliability and security, it is an ideal choice for areas such as industrial automation.
Features:
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 manual or automatic transfer of data configured with DIP switch
Built-in TVS (Transient Voltage Suppressor), effectively suppress ripple voltage and transient spike voltage in the circuit, lightning proof and anti-electrostatic
Built-in auto recovery fuse and protection diodes provide current / voltage stable outputs, provide overcurrent / overvoltage proof, increase shock resistance
Built-in LEDs to indicate power and transceiver status
Breakout SPI control pins for connecting to host control boards such as Arduino
