The module has an internal 4.7 µF bulk capacitor.
However, it is good design practice to add additional
bulk capacitance as required for your application,
i.e. for heavy GPIO usage and/or current draw.

In HV mode, VCC acts as a regulated supply that can power other external devices. The voltage output of VCC can be
configured in software but is limited to no more than VCCH-0.3 V. In System Off mode, VCC can supply no more than 1mA.
