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
RTC3 click™has an integrated trickle charger
that maintains a backup charge through
with an onboard super capacitor. The board
is ideal for applications which require real-
time clocks, calendars and programmed
alarms. It counts seconds, minutes, hours,
date of the month, month, day of the week,
and year with leap-year clock function with
four year calendar.

RTC3 click™carries BQ32000, a real time
clock/calendar with automatic switchover
to backup power supply. The clock frequency
is derived from an onboard 32.768KHz
oscillator. RTC3 click™communicates with
the target board microcontroller through
mikroBUS™I2C lines: SCL, SDA. In addition,
the INT pin serves as a congurable interrupt
output. The board is designed to use a 3.3V
power supply only.
