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/off 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.

Page 10
Page 11
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: USB HID mikroBootloader window
step 1 – Connecting clicker 2 for STM32
01
01
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.

Click OK button after the uploading process is finished.
Press Reset button on clicker 2 for STM32 board and
wait for 5 seconds. Your program will run automatically.
The microcontroller can be
programmed with external
mikroProg™ for STM32 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
from STMicroelectronics.
Outstanding performance, easy
operation and elegant design
are its key features.
3.2 Programming with mikroProg™ programmer
Figure 3-9: mikroProg™ connector

On-board mikroProg™ programmer requires special programming software called mikroProg Suite™
for ARM®. This software is used for programming of all supported microcontroller families with
ARM® Cortex™-M3 and Cortex™-M4 cores. The software has an intuitive interface and SingleClick™
programming technology. To begin, first locate the installation archive on the link bellow:
mikroProg Suite™ for ARM® software
After downloading, extract the package and double click the executable setup file, to start installation.
Figure 3-10: mikroProg Suite™ for ARM® window
Quick guide
Click the Detect MCU button in order to recognize the device ID.
Click the Read button to read the entire microcontroller memory. You can click the Save button to save it to the target HEX file.
If you want to write the HEX file into the microcontroller, first make sure to load the target HEX file using the Load button. Then click the Write button to begin programming.
Click the Erase button to clear the microcontroller memory.

The microcontroller can also be
programmed with the ST-LINK V2 programmer and mikroProg Suite™ for ARM® software. This programmer
connects with the clicker 2 board via
mikroProg to ST-LINK V2 adapter (Figure 3-11).
3.3 Programming with ST-LINK V2 programmer
Figure 3-11: mikroProg™ to ST-LINK™ V2 adaper
Page 17
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 first soldered on
the CN3 connector pads. Then you should
plug the adapter into the ST-LINK V2
programmer (2x10 header), and plug
an IDC10 flat cable in headers,
Figure 3-12.

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
microcontrol ler—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.

clicker 2 for STM32 features
LTC®3586-2, a highly integrated
power management
and battery
charger IC that
includes a current
limited switching
PowerPath manager.
When you solder the
onboard zero-ohm J1
jumper to the LDO position
(Figure 6-1), the LTC®3586-2
will provide an independent,
steady power supply to the MCUs
RTC from the li-polymer battery
or USB, even when the rest of
the system is turned off (or
reset). LTC®3586 also enables battery charging over a USB connection.

crystal oscillator module (X2)
The STM32F407VGT6 microcontroller
is equipped with an internal 16MHz RC oscillator that provides a stable clock
signal. Since the chips have an integrated
PLL, this base frequency is suitable for
further clock multiplication. Board also
contains an additional 25MHz crystal oscillator, as well as a 32.768kHz one,
which provides an external clock for the
internal RTCC module.

Having two mikroBUS™ sockets and an additional connection pad, clicker 2 for STM32 utilizes all of the STM32F407VGT6’s I/Os.
Each of the three UART outputs has its own separate connection pin (either on mikroBUS™ 1 or 2, or on the 2x26 connection pad).
Of the two SPI lines, one is routed to mikroBUS™ 1; the other is shared between mikroBUS™ 2 and the pins on the connection pad.
Same goes for the two available I2C lines.

9.1 mikroBUS™ pinouts
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 webpage for the complete list
of currently available boards:
