2-Channel Isolated RS232 Expansion HAT for Raspberry Pi

This is a 2-channel isolated RS232 expansion HAT designed for Raspberry Pi, with protection circuits such as power supply isolation, ADI magnetical isolation and TVS diode. It is easy to control the 2-channel RS232 via SPI interface.

This product uses SC16IS752 as a controller. SC16IS752 is a dual-channel high-performance UART expansion chip that supports SPI and I2C interfaces. This module uses the SPI interface.

C and Python demo codes are provided for Raspberry Pi, including a quick testing example in python.
