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.

4. Essential features
BarGraph Click™ with it’s
JSB-R102510Z
and
74HC595
ICs gives additional 10
segment light bar display to your design.
The
74HC595
IC contains an 8-bit serial-
in, parallel/serial-out shift register as well
as 8-bit storage register. The storage
registers has parallel 3-state outputs.
Separate clocks are provided for both the
shift and storage register. Shift register
has a direct overriding clear input.

1. Introduction
2
Turn the board upside down so that
bottom side is facing you upwards. Place
shorter parts of the header pins in both
soldering pad locations.
Turn the board upward again. Make sure
to align the headers so that they are
perpendicular to the board, then solder the
pins carefully.
BarGraph Click
™
is an accessory board in
mikroBUS
™
form factor. It’s a compact
and easy solution for adding ten-segment
light bar display to your design. It features
JSB-R102510Z
light bar display as well
as two
74HC595
shift registers. BarGraph
Click
™
communicates with the target board
microcontroller via
mikroBUS
™
SPI (MOSI,
MISO, SCK, CS), RST and PWM lines. The
board is designed to use 3.3V and 5V
power supply. LED diode (GREEN) indicates
the presence of power supply.
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 of the pins are
aligned correctly, push the board all
the way into the socket.
