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
For storing data, the chip onboard RTC5 click
has 64-bytes of battery-backed SRAM and
1 kbit of EEPROM, along with 128 bits of
protected space for storing a unique ID. The
SPI interface has clock speeds of up to 5 MHz
which is enough for a millisecond alarm. The
clock/calendar automatically compensates
for leap years and months shorter than 31
days. The interrupt pin can be used to set up
alarms or events.

RTC5 click carries MCP79510, a real-
time clock/calendar with an SPI interface
(mikroBUS™MISO, MOSI, SCK and CS pins)
and a programmable interrupt for system
output. The clock frequency is derived
from an onboard 32.768KHz oscillator.
For backup power, RTC5 click has a coin-
cell Lithium polymer battery connector.
The board is designed to use a 3.3V power
supply only.
