mikromedia 3 for PIC32MZ CAPACITIVE U S E R M A N U A L
The power supply unit (PSU) provides clean and regulated
power, necessary for proper operation of the mikromedia 3
development board. The host MCU, along with the rest of the
peripherals, demands regulated and noise-free power supply.
Therefore, the PSU is carefully designed to regulate, filter, and
distribute the power to all parts of mikromedia 3. It is equipped
with two different power supply inputs, offering all the flexibility
that mikromedia 3 needs, especially when used on the field
or as an integrated element of a larger system. In the case
when multiple power sources are used, an automatic power
switching circuit with predefined priorities ensures that the
most appropriate will be used.
The PSU also contains a reliable and safe battery charging
circuit, which allows a single-cell Li-Po/Li-Ion battery to be
charged. Power OR-ing option is also supported, providing an
uninterrupted power supply (UPS) functionality when an USB
power source is used in combination with the battery.
