MAX485 Module RS-485 TTL Turn To RS485 MAX485CSA Converter Module For Arduino Microcontroller MCU Development Accessories
Product Description
1. Power supply voltage: 5V
2. Onboard MAX485 chip, a low-power, limited swing rate transceiver for RS485 communication
3.5.08mm spacing 2P terminal block, RS485 communication wiring
4. Can be connected to a microcontroller for control operations
instructions
1. Use two IO ports to control transmission and reception:
RE: Receive switch RE=0: Open RE=1: Close
DE: Launch switch DE=0: Close DE=1: Open
2. Use an IO port to control:
RE and DE are connected to an IO port, IO=0: Only accept, I0=1: Only launch
precautions
1. Pay attention to wiring according to the diagram and do not make mistakes.
2. This document only represents the product parameters at the time of editing, and any changes in the future will not be notified separately.
3. If the system only has RXD and TXD signals without a control IO port, it can be directly turned on and enabled from the outside. However, it should be noted that it can only be used as a transmitter or receiver. Due to the pull-up resistor on the board, when RE and DE are not connected (suspended), they are at a high level, that is, only used as a transmitter. If it needs to be used as a receiver, connect RE and DE to a low level (connected to the GND terminal).
