Waveshare 2-Channel Isolated RS232 Expansion HAT for Raspberry Pi 4B/3B+/3B/2B/B+/A+/Zero/Zero W

Description

Description:

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 the SPI interface. Due to its fast communication, stability, reliability, and safety, it is an ideal choice for fields like industrial automation.

Specifications:

• UART Expansion Chip: SC16IS752
• RS232 Transceiver: SP3232
• Communication Interface: SPI
• Data Rate: 300 ~ 921600 bps
• Operating Voltage: 3.3V / 5V
• Dimensions: 65mm × 56.5mm
• Mounting Hole Size: 3.0mm

Features:

• Standard Raspberry Pi 40PIN GPIO extension header supports Raspberry Pi series boards.
• 2-Channel Isolated RS232 Expansion HAT adopts SC16IS752+SP3232 dual-chip combination, converts SPI to RS232, data rate up to 921600bps.
• Onboard TVS (Transient Voltage Suppressor), effectively suppresses 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.
• 2-Channel Isolated RS232 Expansion HAT comes with online development resources and a manual (examples in C and Python).
