Mosiee TTL to RS485 Module UART Serial Converter

Mosiee TTL to RS485 Module UART Serial Converter Description

Feature: *This module fully considers the 485 bus lightnings protection design and anti-interference design, and has extremely high EMC (electromagnetic compatibility) and EMI (electromagnetic anti-interference) performance. *With standard 2.54 pitch pin header to facilitate your secondary development *It has a 120 ohm matching resistor. Short-circuiting R0 can enable the matching resistor. Short-circuiting is recommended for long-distance transmission. *Supports multi-machine communication, the same network can connect at least 40 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-K485 Material: plastic Color: As shown in the picture Wide voltage power supply (3.0V~30V), the limit voltage is 33V, it is recommended to be used within 30V, and the minimum voltage should be higher than 2.8V. Compatible with 3.3V and 5.0V signals, both can be matched with the module Has extremely high EMC and EMI performance. Operating temperature: -40C to +85C Comes with terminal blocks and silicone wire, very convenient to use. Equipped with RXD and TXD signal indicator lights, allowing you to have a panoramic view of the sending and receiving status. Module size:52mm long, 23mm wide Weight: 11g Package Contents: 1*TTL to RS485 module Notes: This transparent transmission module realizes the mutual conversion of TTL signals and RS485 signals, but everyone must know that 485 is half-duplex communication. This communication method can achieve two-way communication, but it cannot be carried out in both directions at the same time. It must be It is carried out alternately in turns; that is to say, each segment of the communication channel can be the sender or the receiver, but at the same time, the information can only have one transmission direction.
