RS485 RS232 HAT is an isolated RS485 and RS232 expansion board specially designed by Waveshare for Raspberry Pi. It adopts SC16IS752+SP3485, SP3232 scheme, built-in power isolation, ADI magnetic coupling isolation and TVS and other protection circuits.
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.
- Onboard power supply and serial port transceiver indicators, easy to check the module power supply and communication status
- Lead out the SPI control interface for easy access to main control boards such as Arduino
- Provide complete supporting information manuals (C and Python sample programs and user manuals, etc.)
