Power Supply and Mode Switch
The INP301x board is designed to supply power to the INP101x module in following ways:
1.
In standalone mode, power is drawn from USB connector
2.
In shield mode, power is drawn from shield connector
3.
A battery header is also available to provide power to the module
Figure 4: Power supply section
The power supply section is shown in the Figure 4. The INP101x module requires 3.3V supply. The
DPDT switch (U3) selects between USB and Arduino header supply using the common net
Vm_3.3V. The jumper J4 is used to select between battery supply and Vm_3.3V. The same jumper
can be used for measuring current consumption of the module.
