2-Channel Isolated RS232 Expansion HAT for Raspberry Pi

Overview
This is a 2-channel isolated RS232 expansion HAT designed for Raspberry Pi, adopts the SC16IS752+SP3232 solution, with embedded protection circuits such as power 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 an ideal choice for fields like industrial automation.
Features

Standard Raspberry Pi 40PIN GPIO extension header, supports Raspberry Pi series boards
Adopts SC16IS752+SP3232 dual chip combination, converts SPI to RS232, data rate up to 921600bps
Onboard TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, lightning-proof & anti-electrostatic
Onboard LEDs for indicating the power and transceiver status
Breakout SPI control pins, for connecting with host control boards like Arduino
Comes with development resources and manual (examples in C and Python)
