2-Channel Isolated RS232 Expansion HAT for Raspberry Pi

This is a 2-channel isolated RS232 expansion HAT designed for the Raspberry Pi, adopting the SC16IS752+SP3232 solution, with embedded protection circuits including power supply isolation, ADI magnetical isolation and TVS diode.

It's easy to control the 2-channel RS232 via SPI interface. Due to its fast communication, stability, reliability, and safety, it's an ideal choice for uses such as industrial automation.

Note: Cables not included

Features

• Standard Raspberry Pi 40-pin GPIO extension header
• Adopts SC16IS752+SP3232 dual-chip combination, converts SPI to RS232, data rate up to 921600bps
