                  Overview:

                  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, ADI 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.

                  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 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
                  Break0ut SPI control pins, for connecting with host control boards like Arduin0
                  Comes with development resources and manual (examples in C and Python)

                  Specifications:

                  UART expansion chip: SC16IS752
                  RS485 transceiver: SP3485
                  Communication interface: SPI
