Introduction to clicker 2 for PIC18FJ
clicker 2 for PIC18FJ is a compact dev.
kit with two mikroBUS™ sockets for click
board connectivity. You can use it to
quickly build your own gadgets with unique
functionalities and features. It carries the
PIC18F87J50, a 8-bit microcontroller, two
indication LEDs, two general purpose buttons,
a reset button, an on/off switch, a li-polymer
battery connector, a USB Mini-B connector and
two mikroBUS™ sockets. A mikroProg connector
and a 2x26 pinout for interfacing with external
electronics are also provided. The mikroBUS™
connector consists of two 1x8 female headers
with SPI, I2C, UART, RST, PWM, Analog and
Interrupt lines as well as 3.3V, 5V and GND
power lines. clicker 2 for PIC18FJ board can be
powered over a USB cable.

USB 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.

Figure 1-2: Connecting
Li-Polymer battery
You can supply power to the board with a Mini-B 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.
NOTE 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.

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 (RD4
and RE4). 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 (RD7 and RH3) from logic high (1) to logic low (0). In addition to the onboard ON/OFF
switch, two pads (EXT and PSW) allow you to
connect your own external switch.

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.

9.1 mikroBUS™ pinouts
clicker 2 for PIC18FJ employs a solution to optimize
the use of available pins and MCU I/Os. The PWM
SEL jumper (Figure 9-2) enables two modes of
use for the second available PWM line:
1 The default position of the jumper is for
applications when you’re not using the PWM line on
the 1x26 pinout on the right side of the board. This
keeps this PWM available through mikroBUS™ 2
If you resolder the jumper into the second
position, it would turn the PWM line on mikroBUS™
2 into a GPIO. You would use this in scenarios
where you already utilized the PWM through the
1x26 pinout (which would make the PWM pin on
mikroBUS™ 2 unusable)

10. click boards™ are plug and play!
Up to now, MikroElektronika has
released more than 90 mikroBUS™
compatible click boards™. On
the average, one click board
is released per week. It is our
intention to provide you with as
many add-on boards as possible,
so you will be able to expand your
development board with additional
functionality. Each board comes
with a set of working example
code. Please visit the click boards™
