Figure 1-2:
Battery power supply
Figure 1-3:
Screw terminals power supply
The mikromedia+ for PIC32MX7® board can be powered in three different 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 levels 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 01 16MHz
crystal oscillator (X4) circuit that
provides external clock waveform
to the microcontroller OSC1 and OSC2
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 32.768kHz crystal
02
03
01
oscillator (X5) 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.

Accelerometer
module
On board ADXL345 accelerometer is used to measure acceleration in three
axis: x, y and z. Most common use is to determine the screen orientation,
but there are many other fields of usage. Communication between
the accelerometer and the microcontroller is performed
through I2C interface. There is an option to select
the alternate accel address with jumper J3.

transceiver module
The development system features an Ethernet transceiver module ideal for local area networking (LAN). 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 re-transmitted. If you want to establish connection with computer, router or other devices you need to use standard RJ-45
connector which is provided on mikromedia+ SHIELD for PIC32MX7®. Communication lines are also provided over side headers.

16. Buzzer
The board is also equipped with piezo buzzer. It is an electric
component which can be used to create sound when is provided
with electrical signal. This is usually a PWM signal coming
from a microcontroller pin. Frequency of the signal
determines the pitch of the sound and duty
cycle of the signal can be used to
increase or decrease the volume.

The board also contains other useful peripherals such as 01 PIN photodiode, 02 IR receiver, 03 RGB led diode and 04 analog
temperature sensor. PIN photodiode is a type of photo detector. It has high sensitivity and response speed. It is connected to the
microcontroller analog pin RB8. IR receiver is used in infrared remote control systems. The demodulated output signal obtained from
IR module can be directly decoded by a microcontroller. Many of standard data formats are supported. RGB (Red, Green, Blue) diode
can be used as a light indicator. Each color is driven separately by transistor. The analog temperature sensor converts temperature to
analog voltage. It is directly connected to the microcontroller RB9 analog pin. Temperature measurement range of mikromedia+ for
PIC32MX7® board is from -20° C to 70° C.
