Description

This is a dual-channel isolated RS485 extension board specially designed for raspberry PI, which adopts SC16IS752+SP3485 solution embeds with protection circuits such as power supply isolation, ADI magnetical isolation, and TVS diode, etc.

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

What’s on Board:

SC16IS752 UART expansion chip
ADUM1412 digital isolator
PC817 optocoupler
SP3485 RS485 transceiver
B0505LS power supply isolation module
RT9193-33 power chip
SMAJ12CA transient suppress diode array
Auto-recovery fuse
Status indicator
PWR: power indicator
RXD/TXD: UART transceiving indicator
Raspberry Pi GPIO connector: for connecting Raspberry Pi
RS485 terminal
MCU control header: for connecting host control boards like Arduino
120Ω terminal resistor switch
Interrupt pin switch
Operating mode selection
Half-auto: A=0, B=1
Full-auto: A=1, B=0
It is easy to control the 2-channel RS485 for auto-transceiving via the SPI interface. Due to its fast communication, stability, reliability, and safety, it is an ideal choice for fields like industrial automation.
