Mikroe Click RTC3 Manual

RTC3 click
™
1. Introduction
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 configurable interrupt
output. The board is designed to use a 3.3V
power supply only.
2. Soldering the headers
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.

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.

Turn the board upward again. Make sure
to align the headers so that they are
perpendicular to the board, then solder the
pins carefully.
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.
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.
