MAX485 RS485 Transceiver Module TTL UART TTL to RS-485 Module RS-485 Communication Transceiver 5V Microcontroller Development Accessory Board for Raspberry Pi

About this item

1. The MAX485 chip is a low-power chip for RS-485 communication, consuming between 120µA and 500µA, limiting the slew rate transceiver to allow operation over very long cables (up to 4000 feet/1200 meters). serial communication
2. The on-board connection is 5.08mm, and the spacing is 2P. It is convenient for RS-485 communication wiring.
3. All the pins of the chip have been drawn out, and the operation can be controlled by the microcontroller
4. The driver is short-circuit current limited and prevents excessive power dissipation with a thermal shutdown circuit that places the driver output in a high impedance state. The receiver input is fail-safe, which guarantees a logic high output when the input is open circuited.
5. It is specially designed for half-duplex applications.
