Each mikroBUS™ host connector
consists of two 1x8 female headers
containing pins that are most likely
to be used in the target accessory
board. There are three groups of
communication pins: SPI, UART and
I
2
C communication. There are also
single pins for PWM, Interrupt,
Analog input, Reset and Chip
Select. Pinout contains two power
groups: +5V and GND on one
header and +3.3V and GND on
the other 1x8 header. mikroBUS™
host connector perfecty ts into
standard breadboards.
As we in mikroElektronika see it,
plug-and-play devices with minimum
settings are the future in embedded
world. This is why our engineers
have come up with a simple but
brilliant pinout with lines that
most of today’s accessory boards
require, which almost completely
eliminates the need of additional
hardware settings. We called this
new standard the mikroBUS™.
What is mikroBUS™?
mikroBUS™ host connector
mikroBUS™ is not made to be only a
part of our development boards. You
can freely place mikroBUS™ host
connectors in your nal PCB designs,
as long as you clearly mark them
on the silkscreen with mikroBUS™
footprint specications which can be
downloaded from the following link:

mikroElektronika’s portfolio of almost
200 accessory boards is now enriched
by an additional set of mikroBUS™
compatible Click boards™. It is our
intention to provide the community
with as much of these boards as
possible, so you will be able to
expand your designs with additional
functionality and minimim hardware
conguration. Just plug and play.
You are allowed to produce and sell
your own mikroBUS™ compatible
boards, as long as you place
mikroBUS™ logo on the board
silkscreen. It would be nice to
hear about it, so send us an E-mail
to o[e-mail]. You are
not allowed to call it “Click board”
though, because “Click” is the
trademark of mikroElektronika.
