clicker 2 for STM32 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 STM32F407VGT6,
a 32-bit ARM® Cortex®-M4 microcontroller, two
indication LEDs, two general purpose buttons,
a reset button, an on/o switch, a li-polymer
battery connector, a USB Mini-B connector and
two mikroBUS™socket. A JTAG 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 STM32 board can be
powered over a USB cable.

1. Power supply
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.
You can also power the board using a Li-Polymer
battery, via on-board 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.

You can program the microcontroller with a
bootloader which is preprogrammed by default.
To transfer .hex le 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 STM32. 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.

programmer and mikroProg
Suite™ for ARM®software.
The external programmer is
connected to the development
system via 2x5 JTAG
connector soldered on the CN3
connector pads, Figure 3-9.
mikroProg™is a fast USB 2.0
programmer with hardware
debugger support. It supports
STM32 M3 and M4 devices

connects with the clicker 2 board via
mikroProg to ST-LINK V2 adapter
(Figure 3-11).

In order to adjust the ST-LINK™V2 programmer to
be connected to the development system, it is
necessary to provide the appropriate adapter
such as the mikroProg to ST-LINK V2 adapter.
2x5 headers should be rst soldered on
the CN3 connector pads. Then you should
plug the adapter into the ST-LINK V2
programmer (2x10 header), and plug
an IDC10 at cable in headers,

Before attaching
the programming
connector, you
have to solder the
provided 2x5 male
header to the JTAG
(CN3) pads.

Figure 4-1:
Two LEDs, two buttons
and a reset button
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 (PE12
and PE15). 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 (PE0 and PA10) 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.
