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
I2C 1-Wire click™enables the host MCU to
generate properly timed 1-Wire waveforms
to its slave devices. These can be EEPROM
chips, temperature sensors and similar
devices that have momentary high source
current modes. The board features three
jumpers for assigning I2C addresses.

I2C 1-Wire click™carries DS2482, a “bridge
device” that performs bidirectional conver-
sions between I2C masters and 1-Wire slave
devices. The I2C interface (mikroBUS™SCL
and SDA pins) supports both standard I2C
(100kHz max) and fast (400kHz) communi-
cation speeds. In addition to the mikroBUS™
socket, I2C 1-Wire click™has an 8-channel
pinout (each pin an independently operated
1-Wire I/O). The board is designed to use
either a 3.3V or 5V power supply.

10. Disclaimer
The board features a VCC SEL. Jumper (zero
ohm resistor) that allows you to choose
between a 3.3V or 5V power supply. By
default it’s soldered in the 3.3V position.
