Figure 1-3: Battery power supply

Figure 1-4: Adapterconnector power supply

Figure 1-1:mikroProg power supply

Figure 1-2:USB power supply

The mikromedia 7 for STM32F4 board can be powered in four different ways: via two USB connectors using MINI-B USB cable provided

with the board (CN4 or CN11), via battery connector using Li-Polymer battery (CN5) or via adapter connector using adapter 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 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.

5. Crystal oscillators and 2.048V reference

The board is equipped with 1 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 2 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 3 voltage reference to the

microcontroller VREF pin which is 2.048V.

6. microSD Card Slot

Board contains 1 microSD card slot for using 2 microSD cards in your projects.

It enables you to store large amounts of data externally, thus saving microcontroller

memory. microSD cards use Serial Peripheral Interface (SPI) for communication with the

microcontroller. Ferrite and capcitor are provided to compensate the voltage and current

glitch that can occur when pushing-in and pushing-out microSD card into the socket.

Proper insertion of the microSD card is shown in Figure 6-1.

10. USB HOST connection

Figure 10-1: Connecting USB cable to MINI-B USB connector via USB adapter

mikromedia 7 for STM32F4 can also

be used as USB HOST which enables

microcontroller to establish a connection

with the target device (eg. USB keyboard,

USB mouse, etc). The board provides

necessary power supply to the target

via TPS2041B IC. In order to enable the 1 USB HOST cable to be connected

to the board, it is necessary to use the

appropriate 2 MINI-B USB to USB type

A adapter. For proper insertion refer to

Figure 10-1.

When the device is working in

USB HOST mode, it must not be

mounted to other USB HOST.

Since multimedia applications are

getting increasingly demanding, it is

necessary to provide additional memory

space to be used for storing more data.

The flash memory module enables the

microcontroller to use additional 8Mbit

flash memory. It is connected to the

microcontroller via the Serial Peripheral

Interface (SPI).

Figure 13-3: RF transceiver module schematic

mikromedia 7 for STM32F4 is equipped with SPWF01SA, a WiFi

module with an integrated antenna from STMicroelectronics. The

module packs a 2.4 GHz IEEE 802.11 b/g/n transceiver and its

own STM32 ARM Cortex-M3 MCU that offloads the workload from

the main microcontroller on the mikromedia. Full featured TCP/

IP protocol stacks are also integrated. A BOOT jumper (zero ohm

resistor) for updating the firmware on the WiFi module is located

nearby, between the module itself and the WiFi silkscreen markings.

The development board features an Ethernet transceiver module

LAN8720A. It is ideal for local area networking (LAN). If you want to

establish connection with a computer, router or other devices, the

development board also contains a standard RJ-45 connector.

Communication over Ethernet is based on data packets called

frames. Each frame contains source and destination addresses

and error-checking data so that damaged data can be detected

and retransmitted. Signalization LEDs (green and yellow) are on

the opposite side of the board.

16. CAN communication

Controller Area Network (CAN or CAN bus) is a vehicle bus standard designed to allow microcontrollers and devices to communicate with each other within a vehicle without a host computer. CAN is a message-based protocol, designed specifically for automotive applications but now also used in other areas such as industrial automation and medical equipment. mikromedia 7 for STM32F4 is equipped with SN65HVD230 – a 3.3V CAN transceiver and a pair of screw terminals which provide microcontrollers with integrated CAN controller with the necessary physical interface for CAN communication. Make sure to correctly connect negative and positive differential communication lines before using this module.

Node termination jumperIf the board is the first and the last node of the CAN network, then TERMINATION jumper should be placed. If the board is a node in the middle, the jumper should be removed.

Figure 17-2: Buzzer module schematic

The board also contains additional peripherals that can be very

useful, such as 1 PIN photodiode, 2 IR receiver, 3 RGB led

diode and 4 analog temperature sensor. PIN photodiode is a

type of photo detector capable of converting light into the voltage

with high sensitivity and speed of response. It is connected to the

microcontroller analog pin. IR receiver is used for infrared remote

control systems. The demodulated output signal obtained from IR

module can be directly decoded by a microcontroller. Many of existing

standard data formats are supported. RGB (Red, Green , Blue) diode is suitable for light indication in your design. Each of colour is driven

separately by transistor. The analog temperature sensor converts

temperature to analog voltage and it is directly connected to the

microcontroller analog pin. Temperature measurement range of

mikromedia 7 for STM32F4 board is from -20°C to 70°C.
