Microcontroller Microcontroller - UART Protection Anti-interference Ability

DESCRIPTION

Feature:
*This module fully considers the 485 bus s protection design and anti-interference design. It uses an isolation chip to realize the isolation of power supply and signals.
*Adopts standard 2.54 pitch design to facilitate your secondary development
*With 120 ohm matching resistor, short-circuiting RO can enable the matching resistor. Short-circuiting is recommended for long-distance transmission.
*Supports multi-machine communication, the same network can connect at least 128 nodes
*Can be hot-swapped and there will be no signal blocking.
*Anti-interference wiring and copper laying method to prevent signal interference

Specification:
Part name:TTL to RS485 module
Model: XY-5ASK
Material: plastic
Color: As shown in the picture
Wide voltage power supply (3.0V~5.5V)
3.3V and 5.0V signals are compatible and can be matched with the module Xinyi Electric
Power and signal isolation, high performance EMC and EMI, isolation voltage up to 2500VDC
Using imported chips, industrial-grade design, strong anti-interference ability, and powerful 485 protection design, it can be used in industrial sites and harsh outdoor environments.
