1. Power supply
You can supply power to the board with a micro USB cable provided
in the package. On-board voltage regulators provide the appropriate
voltage levels to each component on the board. Power LED (GREEN)
will indicate the presence of power supply.
You can also power the board using a Li-Polymer battery, via onboard
battery connector. On-board battery charger circuit enables you
to charge the battery over USB connection. LED diode (RED) will
indicate when battery is charging. Charging current is ~300mA and
charging voltage is 4.2V DC.

Some click boards need more current than the USB connection can supply. For 3.3V clicks, the upper limit is 750 mA; for 5V clicks, it’s 500
mA. In those cases you would need to use the battery as the power supply, or the vsys pin on the side of the board.

You can program the microcontroller with a bootloader
which is preprogrammed by default. To transfer .hex
file from a PC to MCU you need bootloader software
(mikroBootloader USB HID) which can be downloaded
from:
3.1 Programming with mikroBootloader
Figure 3-2: mikroBootloader window
step 1 – Connecting clicker 2 for PIC18FK
01
To start, connect the USB cable, or if already connected press
the Reset button on your clicker 2 for PIC18FK. Click the Connect
button within 5s to enter the bootloader mode, otherwise existing
microcontroller program will execute.
After the mikroBootloader software is downloaded,
unzip it to desired location and start it.

The microcontroller can be programmed with external
mikroProg for PIC programmer and mikroProg Suite for
PIC® software. The external programmer is connected to
the development system via 1x5 connector Figure 3-9.
mikroProg is a fast USB 2.0 programmer with hardware
debugger support. It supports PIC10®, dsPIC30/33®,
PIC24® and PIC32® devices in a single programmer.
It supports over 570 microcontrollers from
Microchip®. Outstanding performance, easy
operation and elegant design are its key
features.

mikroProg Suite for PIC software
mikroProg programmer requires
special programming software
called mikroProg Suite for PIC. This
software is used for programming
of ALL Microchip® microcontroller
families, including PIC10®, PIC12®,
PIC16®, PIC18®, dsPIC30/33®, PIC24®
and PIC32®. Software has intuitive
interface and SingleClick™ programming
technology. Just by downloading the
latest version of mikroProg Suite your
programmer is ready to program new
devices. mikroProg Suite is updated
regularly, at least four times a year, so
your programmer will be more and more
powerful with each new release.

Figure 4-1:
Two LEDs, two buttons
and a reset button
4. Buttons and LEDs
The board also contains a reset
button and a pair of buttons and
LEDs, as well as an ON/OFF switch.
The Reset button is used to manually
reset the microcontroller—it
generates a low voltage level on the
microcontroller’s reset pin. LEDs
can be used for visual indication of
the logic state on two pins (RH3 and
RD7). An active LED indicates that
a logic high (1) is present on the
pin. Pressing any of the two buttons
can change the logic state of the
microcontroller pins (RF3 and RF2)
from logic high (1) to logic low (0).

5. Power management and battery charger
clicker 2 for PIC18FK features LTC®3586, a highly integrated power management and battery charger IC that includes a
current limited switching PowerPath manager. LTC®3586 also enables battery charging over a USB connection.

6. Oscillators
Board is equipped with 16MHz crystal oscillator (Y1) circuit that provides external clock waveform to the microcontroller
CLKO and CLKI pins. This base frequency is suitable for further clock multipliers and ideal for generation of necessary
USB clock, which ensures proper operation of bootloader and your custom USB-based applications.

PIC18F67K40 microcontrollers has an integrated USB module, which enables
you to implement USB communication functionality to your clicker 2 board.
Connection with target USB host is done over a micro USB connector which is
positioned next to the battery connector.
