1Product 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:
oNINA-B221 and NINA-B222
oNINA-W101 and NINA-W102
oNINA-W131 and NINA-W132
oNINA-W151 and NINA-W152
oNINA-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.

⚠Take care while handling the EVK-NINA-B222 and EVK-NINA-W1x2. Applying force to the NINA
module might damage the internal PIFA antenna.

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.
