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.

1. Introduction
4. Essential features
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.
8x8 B Click™ is an accessory board in
mikroBUS™ form factor. It’s a compact and
easy solution for adding 8x8 BLUE LED matrix
to your design. It features MAX7219 8-digit
LED display driver module as well as 64 BLUE
LED diodes. 8x8 B Click™ communicates
with target board microcontroller via four
mikroBUS™ SPI lines (DIN, DOUT, CLK and
CS). The board is designed to use 5V power
supply only, but it can be used with 3.3V
MCUs as well.
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 of the pins are
aligned correctly, push the board all
the way into the socket.
8x8 B Click™ with it’s MAX7219 IC gives
additional 8x8 BLUE LED matrix to your
design. The MAX7219 is serial input/
output common-cathode display driver
with SPI interface. It has BCD code-B
decoder, analog and digital brightness
control, 8x8 static RAM and several useful
registers.

Once you have done all the necessary
preparations, it’s time to get your click
board up and running. We have provided
the examples for mikroC, mikroBasic and
mikroPascal compilers on our Libstock
website. Just download them and you are
ready to start.
