mikroElektronika 8x8 B Click User manual

1. Introduction
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.

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

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.
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.
