Table 8: Module pin to ESP32 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.
☞
(3) Control of these signals from an external host requires the removal of some resistors as
described in chapter 1.8.1.
☞
(4) These signals are available only on EVK-NINA-W1x6.
1.8.1 UART
To enable a host to control the module through the UART interface on the J3 and J4 connectors,
rather than through the USB connector, the RXD, CTS and DSR pins on the J3 and J4 connectors
must be disconnected from the USB connector. By default, they indicate the signals as presented on
the USB connector. Disconnect the signals by removing the resistors R35, R37 and R39. Removing
the resistors disables control using the USB connector, and all control must subsequently be done
through the J3 and J4 connectors.
1.8.2 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
