Description
Specifications

This is a breakout board for the SP3485 RS-485 transceiver IC, which will convert a UART serial stream to RS-485. The SP3485 is a half-duplex transceiver, so it can only communicate one way at a time, but it can reach transmission speeds of up to 10Mbps. This board requires a very low amount of power and can operate from a single +3.3VDC supply.

Features:

Fully equipped with SP3485 RS-485 transceiver and supporting components
Operates from a single +3.3V supply
Interoperable with +5.0V logic
Driver/Receiver Enable connected to RTS line
-7V to +12V Common-Mode Input Voltage Range
Allows up to 32 transceivers on the serial bus
Driver Output Short-Circuit Protection

Operating voltage range: DC 3.0V ~ 30V
Operating temperature range: -40 ℃ to +85 ℃
Baud rate: 110 ~ 256000bps
The 485 bus is with lightning protection and anti-jamming function, with high EMC, EMI performance. When using for long-distance transmission in the field, the module EARTH side please connect to the ground, can achieve well anti-interference and lightning protection function; for indoor short-distance transmission, it cannot connect to ground.
Standard 2.54 pitch pin
With 120 ohms matching resistance, shorted R0 can be enabled to match the resistance, recommended shorted for long-distance transmission.
Support multi-machine communication, the same network can connect at least 40 nodes.
Can be hot-plugging, there will be no signal plug phenomenon.
Using anti-jamming alignment and copper to prevent signal interference.
