6. Power supply selection
by default. In order to use RTC click with
5V development system, it is necessary to
resolder this jumper to 5V position.
7. Code Examples
Once you have done all the necessary
preparations, it's time to get your click
board up and running. We have provided
the examples for mikroC, mikroBasic and
mikroPascal compilers on our
website. Just download them and you are
ready to start.

end of product lifetime, so if something goes
wrong, we are ready and willing to help!
On-board PWR SEL zero-
ohm resistor (SMD jumper) is
used to determine whether
5V or 3.3V power supply
is used. This resistor is
provided in 3.3V position
