2. Soldering the headers
1. Introduction
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
1
A bipolar Hall eect sensor is sensitive to
both north and south pole magnetic elds.
BI HALL click
™
outputs a HIGH logic level
when exposed to a south pole magnetic
eld, and a LOW logic level when exposed to
a north pole magnetic eld. When removed
from a magnetic eld, the logic level stays
in its previous state. It’s suitable for any
application where alternating north and
south poles are used to ensure switching. For
example, to measure rotary speed by utilizing
a ring magnet with north and south poles.

BI HALL click
™
is a simple solution
for adding a bipolar Hall switch to
your design. It carries the Melexis
US2882 bipolar Hall-effect switch
and a 74LVC1T45 single bit, dual
supply transceiver. BI HALL click
™
communicates with the target board
through the mikroBUS
™
INT line. The
board is designed to use either a 3.3V or
5V power supply (which also defines the
logic level of the output signal).
