1 Kit 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 to easily access the Bluetooth UART interface via 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.

3 Getting started
This chapter describes the basic settings and procedures necessary to get started with the JODYW3 EVK.
☞ Figure 1 shows an overview of the EVK and its main connectors. For more detailed description
of the available connectors and configuration options, see section 4 .
Follow the procedure below to evaluate JODY-W3 series module using EVK-JODY-W3:
1. Connect the internal or external antennas to the EVK:
o EVK-JODY-W374 uses the two internal dual-band antennas by default for any Wi-Fi and
Bluetooth communication.
o EVK-JODY-W377 uses one of the internal antennas by default for Bluetooth, and Wi-Fi is
configured to use SMA connectors.
o The two included external antennas connect to the selected SMA connectors, SMA1 and
SMA2, on the EVK-JODY-W377 board.
☞ For more information about the antenna configuration, see also section 4.10
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 section 4.9.
3. Configure the power supply source as described in section 4.3 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 EVK and supplied PCIe and SDIO adapters
use zero insertion force (ZIF) connectors and 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.
o For PCIe connection, choose 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 and then connect it with the flat cable to the connector (J203) on the EVK, as shown
in Figure 2. The PCIe interface can be used for Wi-Fi communication with the JODY-W3 series

module.
Figure 2: PCIe and USB connectors
o For SDIO connection, connect the micro SDIO adapter card with the flat cable to the SDIO
connector (J204) on the EVK as shown in Figure 3 and insert the adapter card into an SDIO
connector of the host system. The SDIO interface can be used for Wi-Fi, and optionally

Bluetooth, communication with the JODY-W3 series module.
Figure 3: SDIO connector
o A 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 included USB cable to the USB type-C connector on the
EVK (see Figure 2) 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. Refer
to section 4.6 for information how to access the UART interface for Bluetooth directly.
5. Power on the host system. The LEDs on the EVK for the different voltage levels 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 series module as described in the System
integration manual [2].

to the module. The Bluetooth traffic uses the high-speed UART interface.
• SDIO-UART mode: Commands and data for the Wi-Fi traffic is transferred through the SDIO bus
to the module. The Bluetooth traffic uses the high-speed UART interface.
• SDIO-SDIO mode: Commands and data for both the Wi-Fi and Bluetooth traffic is transferred to
the module through the SDIO bus.
DIP switch SW503 is used on the EVK to define the boot up mode and the physical interfaces used for
Wi-Fi and Bluetooth communication. Set each switch ON to pull the configuration signal low (GND,
logic level “0”), and OFF to pull it high (logic level “1”).

☞ The UART interface for Bluetooth can be accessed either directly through J305, or through the
USB type-C connector J205 via a USB-to-UART bridge. For further information about the
Bluetooth UART interface, see section 4.6.
4.10 Antenna interfaces
The evaluation board includes two dual-band 2.4/5 GHz chip antennas (Pulse Electronics W3006) for
Wi-Fi and Bluetooth communication. Three standard 50 Ω female SMA connectors are included to
connect external antennas or measurement instruments. The antenna interfaces are selected by
connecting designated u.FL connectors on the EVK with coaxial RF cables.
The module board has three u.FL connectors which connect to the antenna pins of the JODY-W3
series module. To use any of the chip antennas or SMA connectors on the EVK, connect a coaxial RF
cable between the u.FL connector on the module board and u.FL connector on the carrier board, as
shown in Figure 20 and Figure 21.
Table 11 describes the available radio interfaces of the modules and the default antenna interfaces
which are selected on the EVK.

Appendix
A Known issues
The following issues are known with the latest version of the EVK.
• The USB interface for Bluetooth does not work in the case of VIO=1.8 V, power supply over PCIe
and the USB cable plugged into the host before the host PCIe initialization. To work around this
issue, use external power supplies or plug the USB cable only after PCI initialization.
• When using the EVK-JODY-W3 with NXP i.MX8 series platforms, the SDIO interface cannot be
used to draw the power for the module. To work around this issue, draw power through USB or
external power supplies.
• Reset buttons SW500, SW501 are not working properly. This issue is to be addressed for the next
board revision.
For more information about known issues, recommendations and solutions, contact your local u-blox
support team.
