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
Flame click
™
can operate in two ways. It can
output a continuous analog signal from the
phototransistor, or send an interrupt to the
target board MCU. The onboard potentiometer
allows you to set the exact threshold that will
trigger the interrupt. This will require some ne
tuning as the phototransistor will be sensitive
to the surrounding thermal radiation. Properly
calibrated, ame click
™
can be used in a variety
of safety applications. Fire sensors based on
phototransistors have a faster reaction time
compared to smoke or heat detectors.

Flame click

is a re detection solution. It carries
a PT334-6B NPN silicon phototransistor that’s
covered in black epoxy and therefore sensitive
only to infrared light. A potentiometer lets
you calibrate the sensor for its specic
environment. The board communicates with
the target board microcontroller through the
mikroBUS
™
AN and INT pins. It can use both a
3.3V or a 5V power supply.
