915 Generation Isolated RS485 RS232 Expansion HAT for 4B3B3B2B SPI Control Onboard Protection Circuits

Isolated RS485 RS232 Expansion HAT for Based on 40pin GPIO interface suitable for 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 RS232RS232 full-duplex communication SP3232 transceiver RS485 semifull-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 stable output of current and voltage prevent overcurrent and overvoltage and shock resistance
Onboard transient voltage suppression tube which can effectively suppress the surge voltage and transient voltage in the circuit and protect against 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 for and other control boards
