Instruction 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.) Specifications Serial port expansion chip: SC16IS752 RS485 transceiver: SP3485 RS232 transceiver: SP3232 Communication Interface: SPI Communication rate: 300~921600 bps Operating Voltage: 3.3/5V Dimension: 65mm x 56.5mm Via diameter: 3.0mm How-to-use document/User Manual ://bit.ly/3DNZjTE //bit.ly/3DNZjTE Package Content RS485 RS232 HAT x1 2X20PIN header x1 Standoffs pack (2pcs) x1

Operating Voltage: 3.3/5V. Dimension: 65mm×56.5mm . 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.). Overcurrent/Overvoltage proof, High Stability. 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. 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.
