    Isolated RS485 RS232 Expansion HAT for Raspberry Pi, SPI Control

    Isolated RS485 RS232 Expansion HAT For Raspberry Pi, SPI Control, Onboard Protection Circuits
    Isolated RS485 RS232 HAT For Pi

    Comes with development resources and manual

     
    Features At A Glance
    • Standard Raspberry Pi 40PIN GPIO extension header, supports Raspberry Pi series boards
    • Adopts the combination scheme of SC16IS752, SP3485 and SP3232, converts SPI to one RS485 and one RS232
    • Onboard resettable fuse and protection diodes, ensure the stable output of RS485 current and voltage, prevent over-current and over-voltage, improve shock resistance
    • Onboard TVS (Transient Voltage Suppressor), can effectively suppress surge voltage and transient spike voltage in the circuit, lightningproof & anti-electrostatic
    • Breakout SPI control pins, for connecting with Arduino and other host control boards
    • Comes with development resources and manual (examples in C and Python)
