1Kit description
The JODY-W2 series comprises compact modules based on the NXP 88W8987 chipset family. The
chipsets used in the automotive grade JODY-W2 modules are AEC-Q100 compliant. They enable
Wi-Fi, Bluetooth, and Bluetooth Low Energy (LE) communication, and are ideal for automotive and
industrial applications.
EVK-JODY-W2 allows an external host processor to access several practical features for testing and
evaluating the Wi-Fi and Bluetooth connectivity supported in JODY-W2 series modules, including:
•An external connector to all host interfaces (SDIO and UART)
•PCM interface through an on-board accessible connector
•GPIO pins that are accessible through an on-board connector
•Internal dual-band 2.4/5 GHz antennas for Wi-Fi and Bluetooth
•SMA connectors for external antennas.
•Module interfaces that are all externally available via the pin headers
For more information about JODY-W2 modules, see the JODY-W2 series data sheet [1] and system
integration manual [2].

1.3 Software
JODY-W2 series modules are based on the NXP 88W8987 chipset family. The drivers and firmware
required to operate JODY-W2 series modules are developed by NXP and are already integrated into
the Linux BSP for the NXP i.MX application processors [6] and the MCUXpresso SDK for NXP MCU
devices [8].
The documentation for NXP software releases contains Wi-Fi and Bluetooth release notes and a list
of supported software features. The driver source code is provided free of charge as open-source
software under NXP licensing terms. As open-source software, the drivers can be integrated or ported
to other non-NXP based host platforms. Yocto recipes for the driver (nxp-wlan-sdk, kernel-module-
nxp89xx) and firmware (linux-firmware), that can be used to develop custom Linux-based systems,
are part of the NXP i.MX Linux BSP.
1.3.1 Driver source code
The latest version of the driver source code and Wi-Fi/Bluetooth firmware are available from the
following open-source repositories:
•Wi-Fi driver: https://github.com/nxp-imx/mwifiex
•Firmware: https://github.com/NXP/imx-firmware/
•i.MX meta-layer: https://github.com/nxp-imx/meta-imx
☞Use the repository branches matching the latest Linux BSP release version. At the time of
document publication, this is version 5.15.52_2.1.0.
The Wi-Fi driver uses the TCP/IP stack from the Linux kernel for data transmission and the cfg80211
subsystem in the kernel for configuration and control. The hci_uart driver from the Linux kernel and
BlueZ host stack are used for the Bluetooth part. For further information about initialization and
configuration of the Wi-Fi and Bluetooth features, see also the NXP User Manual UM11490 [7].
Contact your local u-blox support team for information about additional software options for the
JODY-W2 series modules.

2.2 EVK setup procedure
Use the following procedure to evaluate JODY-W2 series modules:
1. By default, internal antennas are selected for any transmission and reception using pig-tail
coaxial cables, as shown in Figure 18. To use external antennas, connect the cables to another
pair of U.FL adapters and then connect the external dual-band antennas to the SMA connectors.
2. Connect the SDIO adapter to the connector on the board.
3. Connect the evaluation board to the host system through the supplied micro or full-size SDIO
adapter card. The evaluation board uses zero insertion force (ZIF) connectors and flat cables to
connect the adapters. To connect the cable, gently flip up the small locking flap of the connector,
align and insert the cable with the blue marking pointing upwards, and then close the locking flap.
4. Check the LEDs. They correspond to different input voltage levels and turn green when the
appropriate levels are reached. At this point, the module should be detected by the host system.
5. For evaluation of the Bluetooth features, use either an SDIO interface (with flat cable shared with
Wi-Fi) or UART (with Type-C USB cable). See also Bluetooth UART interface and Bootstrapping.
6. Install the necessary driver software for JODY-W2 series modules, as described in the system
integration manual [2].
2.3 Host interface for Wi-Fi (1.8 V UHS)
The SDIO interface is the only available option for Wi-Fi communication. Follow the procedure outlined
below to connect the SDIO interface for Wi-Fi:
1. Connect the micro SDIO adapter card with the micro SDIO connector J204 to the board using the
flat ribbon cable. Make sure that the blue strip at the end of the connector faces upwards when
connecting each end of the cable.

UBX-19027118 - R06 Contents Page 10 of 25
C1 - Public
2. Connect the evaluation board to the host system by inserting the adapter card into an SDIO
connector on the host system.
⚠Be careful when inserting the SDIO adapter into the SDIO slot of a laptop. Built-in readers can be
poorly designed and damage more easily than those on more compact development platforms.
2.4 Host interface for Wi-Fi (3.3 V HS)
By default, EVK-JODY-W2 operates with host interface voltage of 1.8 V. For the designs with host
interface voltage 3.3 V, a level shifter is needed to convert the voltage level of the SDIO signals. Only
SDIO High Speed (HS) mode is supported when using a 3.3 V interface voltage.
Figure 3 shows how the level shifter and EVK are connected. See also the level shifter integration
application note [3].
Figure 3: EVK connection to level shifter
⚠Level shifters are voltage sensitive. To avoid damaging the level shifter IC, connect the level shifter
so that host is in the same direction of the micro-SD adapter, as shown in Figure 4.
Figure 4: Level shifter direction
⚠The level shifter is designed to connect with a host platform through the ZIF cable connector only.
It cannot work if connected directly to an SD card slot or adapter through the micro-SD extension
of the level shifter board. For the level shifter to work, position the resistors on the SDIO lines from
a horizontal to vertical orientation, as shown in the Figure 5.
Always connect this end to the host
platform through ZIF cables only.

Always connect to the
EVK-JODY-W2.
