Noun parsing:

unidirectional  : That is, the communication can only be transmitted or received. But can switch direction by EN feet

bidirectional : that is, there is no need to switch the communication direction manually, it is fully automatic to send and receive, and the direction cannot be switched through EN foot, otherwise the computer will be burned out at your own risk.

1. Onboard 485 chip is the 1 low-power, slew-rate limited transceiver for RS-485 communication.

2, with TTL level to 485 signal function, or 485 to TTL signal. mutual rotation

3. The single-chip serial port and other TTL serial port signals can be converted into RS485 signals to realize networking or long-distance communication.

4. On-board connection with 2.54mm spacing wiring pin

5. With serial port pin and direction control pin

6. Working voltage: 3.0-3.6V (low power consumption type)(MAX485 power supply 5V)

Plate function:

This module can be used when the serial port is not enough. Combined with this module, multiple single-chip serial ports can be formed into a network, that is, serial ports can communicate in parallel and send and receive data according to different addresses. At the same time, the communication distance is greatly improved. In RS485 protocol, the maximum communication distance can reach 1000 meters according to the different wires. Therefore, after serial TTL level is converted to RS485 communication, most application requirements can be met in network and distance.
