Isolated RS485 RS232 Expansion HAT Board for Raspberry Pi 4B/3B+/3B/2B/Zero/Zero 2 W/Zero 2 WH, SPI Control Onboard Protection Circuits

Isolated RS485 RS232 Expansion HAT for Raspberry Pi. Based on Raspberry Pi 40pin GPIO interface, suitable for Raspberry Pi series motherboards. Using SC16IS752 and SP3485, SP3232 multi-chip combination scheme, can realize SPI to RS485, RS232, the communication rate is up to 921600bps. Support RS485 and RS232.RS232: full-duplex communication, SP3232 transceiver; RS485: semi/full-automatic communication, SP3485 transceiver. RS485 supports manual or automatic sending and receiving of data, which can be set by DIP switch. RS485 onboard resettable fuse and protection diode can ensure stable output of current and voltage, prevent overcurrent and overvoltage, and improve shock resistance. Onboard TVS (transient voltage suppression tube), which can effectively suppress the surge voltage and transient peak voltage in the circuit, and protect against lightning and static electricity. Onboard power supply and serial port transceiver indicators, easy to check the module power supply and communication status Breakout SPI control pins, for connecting with Arduino and other host control boards.
