Table 8: Module pin to IO signal conversion
☞
(1) Connector/jumper placed inside the brackets indicates that a jumper must be positioned at the
corresponding position of the IO distribution jumpers J14 – J17 if the IO-signal is to be presented
at the designated connector/jumper as mentioned in Table 3.
☞
(2) These IO signals require a second jumper to be positioned at the IO distribution jumper J18 as
mentioned in Table 4.
1.8.1
Power supply
The supply voltage to the EVK-NINA-W1/EVK-NINA-B2 evaluation board can be sourced from the
following connectors:
•
USB (J8)
☞
Depending on your USB source, the USB supply current may be insufficient.
•
External power supply (J23): The external supply voltage must be in the range 5 – 12 V
