Module power concept
The Kit requires a power supply of +5V DC. This can be applied using one of the following options:
•Using one of the interface module
oUSB supply voltage (4.75V to 5.25 V) is available on all connected modules using the
USB plug.
•Using an external power supply and the Signal extender module
o+5V is required
If other voltages than 5V are needed by the module, this is generated onboard with an LDO.
Important Note:
If using an external power supply, ensure the correct amplitude and polarity before power up of the
Kit.
