MikroElektronika's RS485 Click 5 V is an accessory board in mikroBus™ form factor. The on-board ADM485 differential line transceiver from Analog Devices is suitable for high speed bidirectional data communication on multipoint bus transmission lines. It is designed for balanced data transmission and complies with EIA standards RS-485 and RS-422. This transceiver features a differential line driver and differential line receiver. Board operates on 5 V power supply only.

The RS485 Click utilizes the mikroBUS™ platform. The mikroBUS™ standard defines mainboard sockets and add-on boards used for interfacing microcontrollers or microprocessors (mainboards) with integrated circuits and modules (add-on boards). The standard specifies the physical layout of the mikroBUS™ pinout, the communication and power supply pins used, the size and shape of the add-on boards, the positioning of the mikroBUS™ socket on the mainboard, and finally, the silkscreen marking conventions for both the add-on boards and sockets. The purpose of mikroBUS™ is to enable easy hardware expandability with a large number of standardized compact add-on boards, each one carrying a single sensor, transceiver, display, encoder, motor driver, connection port, or any other electronic module or integrated circuit.
