The power supply unit (PSU) provides clean and regulated
power, necessary for proper operation of the mikromedia 5
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 5. It is
equipped with four different power supply inputs, offering all
the flexibility that mikromedia 5 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
external or USB power source is used in combination with the
battery.
