Power Supply
The module is designed to operate within a 2.7V
to 3.3V voltage range. User should ensure a
proper filtering of its power supply: a ferrite bead,
connected to a shunt capacitor to the ground
(10uF typically) is a good practice.

Reset
2.3.1
Module Reset
The microcontroller reset signal is accessible on
the pad of the module. Note that the signal is
floating and not filtered on the module. The reset
signal should be pulled up and filtered with a
shunt capacitor (typically 100nF) to the ground.
To ensure a proper reset of the cortex-M0
microcontroller, the reset signal should remain
low for at least 10ms.
