Figure 1-1:
USB power supply
The mikromedia+ for PIC32MX7® 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 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.

Microcontroller is pre-programmed with USB HID Bootloader,
which can be used to upload new device rmware. To transfer
rmware .HEX le from a PC to MCU you need to use mikroBoot-
loader USB HID application, which can be downloaded from:
Upon download, unzip it to desired location and start the mikro-
Bootloader application:

mikroProg Suite™for PIC®Software
The mikroProg™programmer requires
special programming software called
mikroProg Suite™for PIC®. It can be
used for programming all Microchip®mi-
crocontroller families, including PIC10®,
PIC12®, PIC16®, PIC18®, dsPIC30/33®,
PIC24®and PIC32®. Software has
intuitive interface and SingleClick™pro-
gramming technology. Download the
latest version of mikroProg Suite™
and your programmer is ready to pro-
gram new devices. mikroProg Suite™
is updated regularly, at least four
times a year, so your programmer will
be more and more powerful with each
new release.

The board is equipped with reset button, which is located on the front side of
the board. One press on the reset button will generate a low voltage level
on the microcontroller reset pin (input). Reset button can also be
externally provided through the pin 27 on the side headers.

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
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.
