RS485 Click 3.3V is an accessory board

SN65HVD12

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.

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.

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.

2. Soldering the headers

Turn the board upward again. Make sure

to align the headers so that they are

perpendicular to the board, then solder the

pins carefully.

3. Plugging the board in

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

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

with the board is done using simple UART

interface.
