Description

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)
