EVK-NINA-W1/EVK-NINA-B2 - User guide
1 Product description
1.1 Overview
The EVK-NINA-W1/EVK-NINA-B2 evaluation kit includes an evaluation board, which can be used as a
reference design for the NINA-W1 or NINA-B2 series modules, a quick start guide, and a USB cable.
For the NINA-B221 and the NINA-W1x1 module, the evaluation board is prepared with a U.FL coaxial
connector for connecting the external antenna. The NINA-B222 and the NINA-W1x2 modules have an
onboard PIFA antenna. The NINA_W1x6 have a PCB trace antenna; thus the EVK-NINA-B222, the
EVK-NINA-W1x2 and EVK-NINA-W1x6 evaluation boards do not have a U.FL connector.
The main features of the EVK-NINA-W1/EVK-NINA-B2 are:
• Available in several variants:
o NINA-B221 and NINA-B222
o NINA-W101 and NINA-W102
o NINA-W131 and NINA-W132
o NINA-W151 and NINA-W152
o NINA-W106 and NINA-W156
• All of the module pins are available at connectors or jumpers
• Can be powered through USB (J8) or external power supply (J23)
• Equipped with a Quad High Speed USB to Multipurpose UART/MPSSE IC (FT4232) that allows
serial communication and flashing over USB.
The EVK-NINA-W1/EVK-NINA-B2 evaluation kits are available in the following variants, depending on
the NINA module that is mounted on the EVK:
• EVK-NINA-B221 – Evaluation kit for NINA-B221 module, RF port available on U.FL connector (J21)
• EVK-NINA-B222 – Evaluation kit for NINA-B222 module with onboard PIFA antenna
• EVK-NINA-W101 – Evaluation kit for NINA-W101 module, RF port available on U.FL connector
(J21)
• EVK-NINA-W102 – Evaluation kit for NINA-W102 module with onboard PIFA antenna
• EVK-NINA-W106 – Evaluation kit for NINA-W106 module with a PCB trace antenna
• EVK-NINA-W131 – Evaluation kit for NINA-W131 module, RF port available on U.FL connector
(J21)
• EVK-NINA-W132 – Evaluation kit for NINA-W132 module with onboard PIFA antenna
• EVK-NINA-W151 – Evaluation kit for NINA-W151 module, RF port available on U.FL connector
(J21)
• EVK-NINA-W152 – Evaluation kit for NINA-W152 module with onboard PIFA antenna
• EVK-NINA-W156 – Evaluation kit for NINA-W156 module with a PCB trace antenna
This section describes the main connectors and settings that are required to get started. Figure 1,
Figure 2 and Figure 3 shows the three different antenna variants of the EVK-NINA-W1/EVK-NINA-B2
evaluation board.

1.3 I/O allocation
The block diagram in Figure 4 provides a better understanding of how I/O signals from the module are
made available at connectors and/or interfaces of the EVK.
Sixteen (16) I/O signals (on EVK-NINA-W1x6 17 signals) are available at the middle row of the I/O
allocator. These signals can be distributed to connectors and/or interfaces on the EVK by use of
jumpers to connect the associated middle and outer row pin(s).
The signals IO-12, IO-13, IO-14 and IO-15 can be disconnected from the J4 connector by not
populating the corresponding jumpers at J18. This can be useful if the SDIO signals D2, D3, CLK, and
CMD are directed to the SD card reader (J19).
Signals on the module not connected to any circuits (interfaces, LEDs and switches etc) on the board
are connected directly to J1, J2, J3 or J4 connector.
* Available only on EVK-NINA-W1x6.
Figure 4: Block diagram of EVK-NINA-W10
☞ When reset-n is released, the module pin 27 (IO-0) is read as boot-n (firmware upgrade). When IO-
0 is connected to the module, it must be high during start up for normal operation.
☞ On EVK-NINA-W1x6 the Micro-SD card is placed on the bottom side. Additionally, the NINA-W1x6
module and the J25/J26 and GND pins have changed places.

☞ (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
1.8.3 Low-power Oscillator (LPO)
To enable the LPO on the EVK-NINA-W1/EVK-NINA-B2 evaluation board, certain jumpers must be
disconnected:
• Remove J7-5_J7-6, which control the green part of the RGB LED,
• Remove J5-1_J5-2, which enable the general-purpose switch SW1.
• Optional: Remove J16-9_J16-10, J6-11_J16-12, J16_13-J16_14 and J16_15-J16_16.
These jumpers enable the MicroSD card connector, but contain pull-up resistors on the EVKNINA-W1/EVK-NINA-B2 that affect the current consumption in STOP mode, ESP32 DEEP SLEEP
mode, and ESP32 HIBERNATE power modes.
☞ On EVK-NINA-W1x6, the green part of the RGB LED cannot be controlled.
☞ LPO support in u-connectXpress is pending.
1.8.4 RMII to PHY
The jumpers shown in Figure 10 must be inserted to connect the 10Base-T/100Base-TX PHY with the
associated module RMII interface pins.
When the RMII PHY is connected to the module, the “BLUE-LED” is not available at IO-21.
When the RMII PHY is used in u-connectXpress, neither the RED_LED, BLUE_LED or GREEN_LED
signals are available. Consequently, the RGB LED is not lit at all.
Optional: Jumpers to connect J20
with module JTAG interface
Jumpers to connect Ethernet
PHY with module RMII interface
Figure 10: RMII to PHY jumper configuration
1.8.5 SPI slave interface
u-connectXpress can enable the SPI_H bus to operate as communication interface. For this feature
to be automatically enabled, the host must be connected to the SPI bus according to Table 9. The host
must also follow the requirements described in the u-blox SPI bus, protocol description [28]. This
document describes how to configure alternative pins for the SPI using AT-commands over the
UART/USB.

2 Setting up the evaluation board
The EVK-NINA-W10 is delivered without any software (open CPU) and the software must be
developed by the user.
The EVK-NINA-B2, EVK-NINA-W13, and EVK-NINA-W15 are delivered with the u-blox connectivity
software pre-flashed on the module.
⚠ The module is designed to be used only with the applicable software and only compatible software
can be flashed on the module.
Before connecting to the module, download and install the latest u-blox s-center evaluation software
from the u-blox website.
Plug in external supply power at connector J23 or connect J8 (USB type Micro B) to a USB host using
the USB cable. The status light (DS8) will turn green, indicating that the internal EVK 3.3 V is on.
⚠ When using the evaluation board with external antenna, before powering up the EVK, ensure that
you have connected the 2.4 GHz antenna with the U.FL antenna connector (J21). Failing to do so
may cause undesired operation.
⚠ Be careful to check polarity before connecting external power supply to the evaluation board.
Center conductor is positive (+) and the ring is negative (-).
⚠ The current consumption during startup of the evaluation board can be high.
The operating system will install the correct COM port drivers automatically. The drivers will need to
be installed only when you connect the unit to a new computer for the first time. For more information
about the COM ports and their configuration, see the FTDI FT4232H Datasheet [6].
One COM port will automatically be assigned to the unit by the Windows OS. To view the assigned
COM ports on Windows 7, follow the steps mentioned below:
• Open the Control Panel and click Hardware and Sound.
• Click Device Manager in Devices and Printers. This will open the Device Manager window where
you can view the assigned COM ports.
2.1 EVK without software (open CPU)
The chapter is applicable to the following EVKs.
• EVK-NINA-W101
• EVK-NINA-W102
• EVK-NINA-W106
When using the NINA-W10 open CPU variant, it is not possible to download the u-blox connectivity
software.
The NINA-W10 open CPU variants are to be used when developing custom software based on the
Espressif SDK ESP-IDF. Before compiling custom software, the ESP-IDF must be configured for the
NINA-W10 open CPU variant.
More information on this topic can be found in the NINA-W1 system integration manual [7].
