The Waveshare's Isolated RS485 RS232 Expansion HAT is an isolated RS485 and RS232 expansion board specially designed for Raspberry Pi. It adopts SC16IS752+SP3485, SP3232 scheme, built-in power isolation, ADI magnetic coupling isolation and TVS and other protection circuits. The board features TVS (Transient Voltage Suppressor) and a resettable fuse, which can effectively suppress surge voltage and transient spike voltage in the circuit, improve shock resistance.
Features
-
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
-
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.
