    2-Channel Isolated RS485 Expansion HAT for Raspberry Pi

    2-Channel Isolated RS485 Expansion HAT For Raspberry Pi, SC16IS752+SP3485 Solution, With Multi Onboard Protection Circuits

    Bulit-In Power Supply Isolation, Magnetical Isolation, And TVS Diode, Etc.


    Features:

    This is a 2-channel isolated RS485 expansion HAT designed for Raspberry Pi, adopts the SC16IS752+SP3485 solution, with embedded protection circuits such as power supply isolation, magnetical isolation, and TVS diode, etc.
    It is easy to control the 2-channel RS485 for auto transceiving via SPI interface. Due to its fast communication, stability, reliability, and safety, it is an ideal choice for fields like industrial automation.

    • 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, lightningproof & anti-electrostatic
    • Onboard resettable fuse and protection diodes, ensures the current/voltage stable outputs, provides over-current/over-voltage proof, and improves shock proof performance
    • Onboard LEDs for indicating the power and transceiver status
    • Breakout SPI control pins, for connecting with host control boards like Arduino
    • Comes with online development resources and manual (examples in C and Python)
