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.t

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:

To start, connect the USB cable, or if already connected press
the Reset button on your clicker 2 for PIC24. 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 1100 microcontrollers
from Microchip®. Outstanding performance,
easy operation and elegant design are its key
features.

mikroProg Suite for PIC24®software
mikroProg programmer requires
special programming software called
mikroProg Suite for dsPIC®. 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

4. Buttons and LEDs
The board also contains a 01 reset button and a
pair of 02 buttons and 03 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 (RG13 and RE8). 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 (T2 and T3) from logic high
(1) to logic low (0).

5. Power management and battery charger
clicker 2 for PIC24 features LTC®3586-2, 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 8MHz crystal
oscillator (X1) 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.
There is also 32.768 KHz crystal oscillator
for the RTC

PIC24 microcontrollers have 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.
