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.
