Waveshare 2-channel Isolated Rs232 Expansion Hat For Raspberry Pi

This is a 2-channel isolated RS232 expansion HAT designed for , adopts the SC16IS752+SP3232 solution, with embedded protection circuits such as supply isolation, ADI magnetical isolation, and TVS diode, etc.It is easy to control the 2-channel RS232 via SPI interface. Due to its fast communication, stability, reliability, and safety, it is a perfect choice for fields like industrial automation.Standard 40PIN GPIO extension header, supports series boards. Adopts SC16IS752+SP3232 chip combination, converts SPI to RS232, data rate up to 921600bpsOnboard TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, -proof & anti-electrostatic. Onboard LEDs for indicating the and transceiver statusBreakout SPI control pins, for connecting with host control boards like Comes.UART expansion chip: SC16IS752RS232 transceiver: SP3232Communication interface: SPIData rate: 300 ~ 921600 Operating voltage: 3.3V / 5VMounting hole size: 3.0mmcolor:BlueMaterial:PCBsize:65mm x 56.5mmPackage Contents:1 x 2- RS232 HAT1 x 2X20PIN female pin header1 x Screws kitOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
