1. Introduction
RS485 Click 3.3V is an accessory board
in
in
mikroBus™
form factor. The on-board
SN65HVD12
differential line transceiver
is suitable for high speed bidirectional
data communication on multipoint bus
transmission lines. It is designed for balanced
data transmission and complies with EIA
RS-485 standard. This transceiver features
a differential line driver and differential line
receiver. Board is set to use 3.3V power
supply only.

Once you have soldered the headers your
board is ready to be placed into desired
mikroBUS™ socket. Make sure to align the
cut in the lower-right part of the board
with the markings on the silkscreen at the
mikroBUS™ socket. If all the pins are aligned
board is ready to be placed into desired
mikroBUS™ socket. Make sure to align the
cut in the lower-right part of the board
with the markings on the silkscreen at the
mikroBUS™ socket. If all the pins are aligned
correctly, push the board all the way
into the socket.

4. Using the board
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.

Turn the board upward again. Make sure
to align the headers so that they are
perpendicular to the board, then solder the
pins carefully.

Turn the board upside down, so that
bottom side is facing you upwards. Place
shorter parts of the header pins in the
both soldering pad locations.

Before using your click board, make sure
to solder the provided 1x8 male headers
to both sides of the board. Two 1x8 male
headers are included with the board in
the package.
