RS485 click 5V carries the ADM485 differential line transceiver from Analog Devices. It is designed for balanced data transmission and complies with EIA standards RS-485 and RS-422. The click is designed to run on a 5V power supply. RS485 5V click communicates with the target microcontroller over UART interface, with additional functionality provided by the PWM pin on the mikroBUS™ line.

ADM485 features

The ADM485 is a differential line transceiver suitable for high-speed bidirectional data communication on multipoint bus transmission lines. It is designed for balanced data transmission and complies with both EIA Standards RS-485 and RS-422. The part contains a differential line driver and a differential line receiver. Both the driver and the receiver may be enabled independently. When disabled, the outputs are tri-stated.

Up to 32 transceivers may be connected simultaneously on a bus, but only one driver should be enabled at any time. It is important, therefore, that the remaining disabled drivers do not load the bus. To ensure this, the ADM485 driver features high output impedance when disabled and also when powered down.

How the click works

There are four screw terminals on the board. Those marked with “+” and “-” are RS485 differential high and differential low communication lines. We added two more terminals for VCC and GND reference if needed for further interfacing. Communication with the board is done using simple UART interface.

Pinout diagram

This table shows how the pinout on RS485 click 5V corresponds to the pinout on the mikroBUS™ socket (the latter shown in the two middle columns).

Notes Pin Mikrobus logo.png Pin Notes
NC 1 AN PWM 16 R/T Receive/transmit
NC 3 CS TX 14 RX UART data receive
NC 4 SCK RX 13 TX UART data transmit
NC 7 3.3V 5V 10 +5V Power supply

Jumpers and settings

Designator Name Default Position Default Option Description
J1 PWR. SEL. Right 5V Do not touch, not selectable by user
J2 Bias Enable ON
J3 Bias Enable ON
J4 Term. ON

If the board is the first node of the RS485 network, all three jumpers J2-J4 should be placed. If the board is a node in the middle, all jumpers should be removed. If the board is the last node of the RS485 network, place only J4 termination jumper.
