Blackberry pie dual channel isolation RS232 extending board module SC16IS752 + SP3232 scheme

■ product description [self-introduction] I am the RS232 expansion board with two-channel isolation designed for raspberry PI, adopting SC16IS752+SP3232 scheme, with built-in power isolation, ADI magnetic coupling isolation and TVS protection circuit. I operate simple, through the SPI| interface can control two RS232 communication, communication speed is fast, stable, reliable, safe and other characteristics, can be applied to the field of industrial automation. [my characteristics] ● based on Raspberry Pi 40pin GPIO interface, suitable for Raspberry Pi series motherboard ● using SC16IS752 and SP3232 dual chip combination scheme, can achieve SP to RS232, communication rate up to 921600bps ● on-board TVS transient voltage suppression tube can effectively suppress surge voltage and transient peak voltage in the circuit to prevent lightning and static electricity ● on-board power supply and serial port transceiver indicator light, convenient to check the module power supply and communication status ● SPI control interface is introduced to facilitate access to Arduino and other main control board ● provide a complete companion information manual (C and python sample programs and user manuals, etc.)
