Once you have soldered the headers your
board is ready to be placed into 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.

4. Board applications
RTC2 click is ideal for applications which
require real-time clocks, calendars and
programmed alarms. Communication with
the board is done over standard I
2
C interface.
The Real-Time Clock (RTC) counts seconds,
minutes, hours, date of the month, month,
day of the week, and year with leap-year
clock function with four year calendar.
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
bottom side is facing you upwards. Place
shorter parts of the header pins in the
both soldering pad locations.
Before using your click board, make sure
to solder the provided 1x8 male headers
to both sides of the board. Two 1x8 male
headers are included with the board in
the package.
