The mikromedia+ for STM32 ARM®is a compact development
system with lots of on-board peripherals which allow
development of devices with multimedia contents. The central
part of the system is a 32-bit ARM®Cortex™-M4 STM32F407ZG
144-pin microcontroller. The mikromedia+ for STM32 ARM®
features integrated modules such as stereo MP3 codec, 4.3’’ TFT
480x272 touch screen display, accelerometer, microSD card slot,
buzzer, IR receiver, RGB LED diode, PIN photodiode, temperature
sensor, 2.4GHz RF transceiver, Ethernet transceiver, 8 Mbit ash
memory, RTC battery, Li-Polimer battery charger etc. The board
also contains MINI-B USB connector, power screw terminals, 2x5
JTAG connector, two 1x26 connection pads, ON/OFF switch and
other. It comes pre-programmed with USB HID bootloader, but
can also be programmed with external programmers, such as
mikroProg™ for STM32 or ST-LINK programmer. Mikromedia
is compact and slim, and perfectly ts in the palm of your hand,
which makes it a convenient platform for mobile and other
multimedia devices. We have also prepared a mikromedia+
SHIELD for STM32 ARM® extension board which enables you
to easily expand the functionality of your board.

Figure 1-1:
USB power supply
The mikromedia+ for STM32 ARM® board can be powered in three dierent ways: via USB connector using MINI-B USB cable provided
with the board (CN4), via battery connector using Li-Polymer battery (CN5) or via screw terminals using laboratory power supply
(CN3). After you plug in the appropriate power supply turn the power switch ON (SW1). The USB connection can provide up to 500mA
of current which is more than enough for the operation of all on-board modules and the microcontroller as well. If you decide to use
external power supply via screw terminals, voltage values must be within 2.5-12V DC range. Power LED ON (GREEN) indicates the
presence of power supply. On-board battery charger circuit MCP73832 enables you to charge the battery over USB connection or via
screw terminals. LED diode (RED) indicates when battery is charging. Charging current is ~250mA and charging voltage is 4.2V DC.

You can program the microcontroller with bootloader which is pre
programmed into the device by default. To transfer .HEX le from
a PC to MCU you need bootloader software (mikroBootloader
USB HID) which can be downloaded from:
After software is downloaded unzip it to desired location and
start mikroBootloader USB HID software.

4. RTC Battery and Reset Button
mikromedia+ for STM32 ARM®
features an RTC battery holder
for microcontroller RTC module.
Battery is used as alternate source
of power, so the RTC module can
continue to keep time while the
primacy source of power is o or
currently unavailable. Three types
of coin battery are supported:
CR1216, CR1220 and CR1225.
The board is equipped with reset
button, which is located on the front
side of the board. If you want to reset
the circuit, press the reset button. It
will generate low voltage level on
the microcontroller reset pin (input).
A reset can also be externally
provided through the
pin 27 on the side
headers.

The board is equipped with 01 25MHz
crystal oscillator (X5) circuit that
provides external clock waveform
to the microcontroller OSCO and OSCI
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. The board also contains 02 32.768
kHz crystal oscillator (X4) which provides external clock
for internal RTCC module. Microcontroller ADC requires an accurate
source of reference voltage signal. That is why we provide the external
03 voltage reference to the microcontroller VREF pin which is 2.048V.
