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
Fan click supports PWM speeds from 9.5Hz
to 29 KHz, in four programmable frequency
bands. The control algorithms and the clock
inside the circuit allow you to regulate the RPM
of a given fan with 1% accuracy in the 500-16k
RPM range. The TACH pin gives feedback on
the fan’s operation. The IC also incorporates
detection of aging fans, and alert on fan stall
(the fan driver even attempts to x a stalled
fan while sending the interrupt) These alerts
are sent through the mikroBUS™INT pin.

Fan click carries an EMC2301 controller for
powering and regulating the operation of
four-wire fans, which are commonly utilized
as coolers in computers and other electronics.
The top of the board features two pairs of
screw terminals with PWM, 5V power supply,
TACH and GND pins. The communication
with the target MCU is done through the
mikroBUS™ I2C interface, with an additional
INT pin. Board is designed to use 3.3V power
supply, but also works with 5v logic.

The pins on Fan click are both 3.3V or 5V
tolerant, so you can use both logic levels
(3.3V and 5V). Board is designed to use 3.3V
power supply only.
