Waveshare 2-Channel Isolated RS232 HAT For Raspberry Pi - SC16IS752+SP3232 With Protection Circuits

About This Product

If you're working on industrial automation or need reliable serial communication for your Raspberry Pi projects, this Waveshare RS232 expansion HAT is exactly what you need! It gives you two fully isolated RS232 channels that convert from SPI interface, with data rates up to an impressive 921600bps. The SC16IS752+SP3232 chip combination handles the conversion smoothly, while the built-in protection circuits including power supply isolation, ADI magnetic isolation, and TVS diodes protect your Pi from voltage spikes, electrostatic discharge, and other electrical nasties. It fits perfectly on the standard 40-pin GPIO header of Raspberry Pi boards, and the 65x56.5mm size doesn't take up much space. You get status LEDs to see what's happening with your data transmission, and they even break out the SPI control pins so you can connect it to other microcontrollers like Arduino if needed. The package includes development resources with examples in both C and Python, so you can get up and running quickly. This isn't just for hobbyists - the isolation and protection features make it industrial-grade reliable for applications where communication stability really matters. Whether you're connecting to legacy industrial equipment, scientific instruments, or any device that still uses RS232, this HAT provides a robust solution that won't let you down. The construction feels solid, and having two independent channels means you can interface with multiple devices simultaneously. Just remember - the Raspberry Pi and serial cables aren't included, so you'll need those separately. For anyone needing reliable serial communication on their Pi, this HAT delivers professional performance without the professional price tag!
