The power supply unit (PSU) provides clean and regulated power, necessary
for proper operation of the Clicker 4 for STM32 development board. It is
equipped with three different power supply inputs, offering all the flexibility
that Clicker 4 for STM32 needs, and a reliable and safe battery charging
circuit, which allows a single-cell Li-Po/Li-Ion battery to be charged.

sources to be used, offering unprecedented flexibility: when powered by a
Li-Po/Li-ION battery, it offers an ultimate degree of autonomy.
Power is not an issue even if it is powered over the USB cable. It can be
powered over the USB-C connector, using power supply delivered by the
USB HOST (i.e. personal computer), USB wall adapter, or a battery power
bank. There are two power supply connectors available, each with its
