1. Power supply voltage: 5V<\/p>\n

2. Onboard MAX485 chip, a low-power, limited swing rate transceiver for RS485 communication<\/p>\n

3.5.08mm spacing 2P terminal block, RS485 communication wiring<\/p>\n

4. Can be connected to a microcontroller for control operations<\/p>\n

 <\/p>\n

instructions<\/p>\n

1. Use two IO ports to control transmission and reception:<\/p>\n

RE: Receive switch RE=0: Open RE=1: Close<\/p>\n

DE: Launch switch DE=0: Close DE=1: Open<\/p>\n

2. Use an IO port to control:<\/p>\n

RE and DE are connected to an IO port, IO=0: Only accept, I0=1: Only launch<\/p>\n

<\/p>\n

precautions<\/p>\n

1. Pay attention to wiring according to the diagram and do not make mistakes.<\/p>\n

2. This document only represents the product parameters at the time of editing, and any changes in the future will not be notified separately.<\/p>\n

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).<\/p>\n
