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
The DS2401 IC consists of a factory-
lasered 64-bit ROM that includes a unique
48-bit serial number, an 8-bit CRC, and an
8-bit family code. The data is transferred
serially through the 1-Wire interface. The
unique number can then be used as a PCB
identication, to establish a network node
ID, for equipment registration and similar
purposes. Additionally, the multidrop
capability of DS2401 enables multiple devices
to reside on a single data line.

Unique ID click™carries DS2401, an en-
hanced silicon serial number IC. It’s a low
cost solution for providing a unique reg-
istration number to your design. The chip
uses 1-Wire communications for interfacing
with the target board microcontroller, either
through a GP1 or GP0 pin (here in place of
the default AN and PWM mikroBUS™pins).
The board is designed to use either a 3.3V or
5V power supply.
