1Kit description
JODY-W3 series modules provide complete short-range transceiver solutions based on the NXP
chipset 88Q9098.
Intended for the most advanced in-car infotainment and connectivity systems, JODY-W3 series
modules deliver the highest data rates in Wi-Fi using advanced Wi-Fi 6 802.11ax technology. The
modules operate in concurrent dual-bands, Wi-Fi 2.4 and 5 GHz, dual-MAC, and 2x2 MIMO, and
support Bluetooth 5.1 features like extended advertising, long range, and 2 Mbit/s (PHY) data rates.
The modules require a host processor running Linux or Android and connect to the host processor
through either PCIe or SDIO for Wi-Fi, SDIO or high-speed UART for Bluetooth, and PCM/I2S for
Bluetooth audio.
EVK-JODY-W3 allows an external host processor to access several practical features for testing and
evaluating the Wi-Fi and Bluetooth connectivity supported in JODY-W3 series modules, including:
•External connectors to all host interfaces (PCIe, SDIO and UART)
•USB interface for easy access the Bluetooth UART interface through a USB-to-UART bridge
•Digital and analog audio interfaces for Bluetooth
•Two internal dual-band 2.4/5 GHz antennas for Wi-Fi and Bluetooth.
•Three SMA connectors for external antennas.
•GPIO pins and other module interfaces are accessible through pin headers
•Multiple power supply options
For more information about JODY-W3 modules, see the JODY-W3 series data sheet [1] and system
integration manual [2].

1.3 Software
JODY-W3 series modules are based on the NXP 88Q9098 chipset. The drivers and firmware required
to operate JODY-W3 series modules are developed by NXP and are already integrated into the Linux
BSP for the NXP i.MX application processors [5].
1
The documentation for the software releases from NXP 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 under NXP license terms. Being open source allows the drivers to be integrated or ported to
other non-NXP based host platforms. Yocto recipes for the driver and firmware, that can be used to
develop custom Linux-based systems, are part of the NXP i.MX Linux BSP.
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://source.codeaurora.org/external/imx/mwifiex/
•Firmware: https://github.com/NXP/imx-firmware/
☞Use the repository branches matching to the latest Linux BSP release version. At the time of
publication, this is release 5.10.52_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 JODY-W3 system integration
manual [2] and the NXP User Manual UM11490 [6].
Contact your local u-blox support team for information about additional software options for the
JODY-W3 series modules.

2Getting started
This chapter describes the basic settings and procedures to get started with EVK-JODY-W3.
☞An overview of the EVB and its main connectors is shown in Figure 1. For more detailed
description of the available connectors and configuration options, see Board description.
Follow the procedure below to evaluate JODY-W3 series module using EVK-JODY-W3:
1. Connect the coaxial cables to the U.FL connectors on the module board and internal antennas on
the carrier board; or to SMA connectors for use with external antennas or conducted test setup.
The default antenna configuration is described below:
oEVK-JODY-W374 uses both of its two internal dual-band antennas for Wi-Fi and Bluetooth
communication.
oEVK-JODY-W377 uses one of its two internal antennas for Bluetooth, and Wi-Fi
communication is configured for use through SMA connectors SMA1 and SMA2. Connect
the two supplied external antennas to the selected SMA connectors on the EVB.
For more information about the antenna configuration, see also Antenna interfaces.
2. Set DIP switch SW503 to select the host interfaces for Wi-Fi and Bluetooth from the possible
combinations PCIE-UART, SDIO-UART or SDIO-SDIO, as described in Bootstrapping.
3. Configure the power supply source as described in Power supply configuration and shown in
Table 5. The most common configuration uses the Wi-Fi host interface as the supply source,
which can be either PCIe or SDIO.
4. Connect the host interfaces to the host system. The EVB and supplied PCIe and SDIO adapters
use zero insertion force (ZIF) connectors with flat cables for connecting the adapters. To connect
the cable, gently flip up the small locking flap of the connector, align and insert the flat cable with
the blue marking pointing upwards, and then close the locking flap.
oFor PCIe connection to the host, use either the M.2 or the mini-PCIe adapter depending on
the available connector on the host platform. First, plug the adapter into the PCIe connector
on the host system. Then connect it with the flat cable to the connector (J203) on the EVB,
as shown in Figure 2. The PCIe interface can be used for Wi-Fi communication with the
JODY-W3 series module.

oFor SDIO connection, connect the supplied micro SDIO adapter card with the flat cable to the
SDIO connector (J204) on the EVB, as shown in Figure 3. Insert the adapter card into an SDIO
connector of the host system. The SDIO interface can be used for Wi-F and optionally
Bluetooth communication with the JODY-W3 series module.
Figure 3: SDIO and USB connectors
oA high speed UART interface can be used for Bluetooth communication with the JODY-W3
series module. A USB-to-UART bridge is included on the evaluation board. To use the Bluetooth
interface through USB, connect the supplied USB cable to the USB type-C connector on the
EVB and connect it to a USB interface on the host system. Make sure that jumper J400 is
bridged (default setting) to enable Bluetooth communication over USB. For information about
accessing the UART interface for Bluetooth directly, see also Bluetooth host interface.
5. Power on the host system. The LEDs on the EVB indicate the status of the different voltage rails
and should turn green to indicate proper power supply. At this point, the module should be
detected by the host system.
6. Install the necessary driver software for the JODY-W3 module, as described in the JODY-W3
system integration manual [2].

3.3 Power supply configuration
JODY-W3 series modules must be supplied with 1.8 V (1V8), 3.3 V (3V3), and a VIO voltage that can
be either 1.8 V or 3.3 V. The power supply for the EVB can be provided over the different host
interfaces or from external sources.
The following power supply options are available on the EVB:
•PCIe, SDIO, USB interfaces: The EVB is powered through the host interface. All internal voltages
are generated by DC-DC converters on the EVB.
•Common external power supply: The EVB can be connected to an external (5 V to 24 V) power
supply through a 2.1 x 6.3 mm DC power jack (J11). DC-DC converters are used for generating all
the required internal voltages.
•Separate external supplies: All the individual, 3V3, 1V8,and VIO voltage rails are supplied from
external power sources through the connectors J101-J103.
Figure 7 shows the external connectors and jumpers used for configuring the different power supply
options.

3.6 SDIO interface
The EVB can be connected through a micro SDIO connector for Wi-Fi communication with the host
system. The SDIO connector can optionally be used for Bluetooth

.
The SDIO host interface connector (J204) is shown in Figure 13.
Figure 13: SDIO interface connector
All signals except VDD_SDIO are directly connected to the JODY-W3 module through 22 Ωseries
resistors connected on the module board.
VDD_SDIO can be used for supplying the EVB from the SDIO interface. The SDIO signals are powered
by the 1V8 voltage domain.
☞Pull-up resistors for the SDIO lines are not installed on the EVB because they are typically
included in the host CPU. The EVB carrier board has the provision to install pull-up resistors if
needed by the design.
