2. Soldering the headers
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.
Turn the board upward again. Make sure
to align the headers so that they are
perpendicular to the board, then solder the
pins carefully.
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.
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
Incremental encoders output A and B pulses
which are out of phase to each other, ideally
by 90º. The
LS7366R CMOS
counter takes
these signals as inputs. The decoded input is
then used for non-quadrative, up/down, free
running counting (the IC has many count-
ing modes). Applications include measure-
ment of the direction and RPM of DC motor
shafts. This data can be used for monitoring
and ensuring the proper operation of shafts
in industrial, robotic and a number of other
domains. The chip has multiple operating
modes.

Counter click carries an
LS7366R
quadra-
ture counter. The top of the board has a
pinout for interfacing with incremental en-
coders. The interface has ENCA and ENCB
pins, along with ENCI, which is a program-
mable index. On the other side, Counter
click communicates with the target board
microcontroller through the mikroBUS™
SPI interface (CSK, MISO, MOSI), plus enable
(CNT EN) and interrupt (LFLAG or DFLAG)
pins. The board can use either a 3.3V or a
5V power supply.
