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
RTC4 click has an integrated backup energy
source that maintains a charge with an
onboard coin cell supercapacitor. Being a
1-Wire click board
™
, RTC4 click can operate
in a microLAN network (a network of 1-Wire
devices that are all associated with a master
device). To indentify it in a network, the
DS2417 IC has a factory lasered and tested
64-bit registration number. RTC4 click is
ideal for applications that require realtime
clocks, calendars and programmed alarms.

RTC4 click carries DS2417, a real time clock/
calendar with a 1-Wire MicroLAN interface
and a programmable interrupt for system
output. The clock frequency is derived from an
onboard 32.768KHz oscillator. The clock has
an accuracy of +/-2 minutes per month at a
25 degrees Celsius temperature. Depending
on the position of the onboard jumper, RTC4
click communicates with the target board
MCU either through mikroBUS™ AN or PWM
pin (here, GPI01, GPIO0), plus the INT pin. The
board is designed to use either a 3.3V or 5V
power supply.
