Development Kit connections
A good platform to experiment with the power saving capabilities is the Eurotech development kit; using this
system you can minimize the number of power connections wired in a safe way over the motherboard.
We suggest using the same reference colours listed in Table 8 with AWG18 wire.
The connections you need to realize are limited and shown in the following image:

Figure 6. DTK Power Saving Connections
In this application note we assume that you are using a development system where a CPU-1450 is installed
with the connections described on Figure 6.
Warning:
Handle the module with care, considering that the board remains supplied even when it
is not operating. Remove the mains supply from the system when you need to work on
the development kit.
