RS232
1. Introduction
RS232 click is a simple solution for adding
™
RS232 serial communications to your design.
The board features a standard RS232
DB9 port and a MAX3232 IC, along with
mikroBUS
a ™ host socket, three jumpers
and a power indicator LED. RS232 click
communicates with the target board through
mikroBUS RX (RXD), TX (TXD), CS (RTS), and
™
INT (CTS) lines. RS232 click is designed to
™
use either a 3.3V or 5V power supply.

2. Soldering the headers
Before using your click board, make sure
™
to solder 1x8 male headers to both left
and right side of the board. Two 1x8 male
headers are included with the board in
the package.

Turn the board upside down so that
the bottom side is facing you upwards.
Place shorter pins of the header into the
appropriate soldering pads.

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 the
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. Essential features
The RS232 DB9 port (9 pins) and
the MAX3232 IC constitute a serial
communications connector. RS232 is mostly
used for industrial machines, networking
equipment and scientific instruments, as
well as for computer peripherals. The board
features two jumper positions to connect
RTS (J2) and CTS (J3) lines to the target
board (zero-ohm SMD jumpers not provided
in the package).
