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.

2.5 Host interface for Bluetooth
JODY-W2 series modules support a high-speed UART interface for Bluetooth communication.
A USB-to-UART bridge (FTDI FT231X) is included on the evaluation board. Follow the procedure
outlined below to connect the board to a host system through USB.
1. Connect one end of the USB cable to the Bluetooth USB connector on the board.
2. Connect the other end of the USB cable to the host system.
3. Check that jumper J400 is bridged to enable Bluetooth communication over UART through FTDI.
☞The 4-pin UART interface of the JODY-W2 series modules can be directly accessed through
the pins on the Bluetooth UART connector J305 of the EVK. For information on how to use the
Bluetooth UART on the evaluation board, see also Bluetooth host interface.
These resistors must be connected
in vertical positions.

3.3 Power supply configuration
JODY-W2 series modules are supplied with VBAT (3.3 V), 1V8 (1.8 V), and VIOvoltage (either 3.3 V or
1.8 V). Different interfaces and external sources can also provide input voltages to the module.
Power to EVK-JODY-W2 can be supplied through different interfaces:
•SDIO interface: The host connector for all Wi-Fi and Bluetooth (optional) communication can be
used to generate the power needed for operation.
•USB: If Bluetooth is connected through USB, the bus can also be used as a power supply.
•External power supply: EVK-JODY-W2 can be powered by an external 5 V to 24 V supply using a
terminal connector or power jack. In this case, a DC-DC converter is used for generating all the
required internal voltages. S1 is used to switch on the board when supplied through J100 (terminal
connector) or J11 (power jack). Only one supply should be used at a time. The power jack should
be 2.1 mm in diameter with positive polarity at the center.
•Individual supply: All necessary voltage levels, VBAT, VIO, and 1V8 have pinouts that can be
connected individually using an external power source.

3.4 Bootstrapping
JODY-W2 supports the following host interface combinations:
•SDIO-UART mode: Commands and data for the Wi-Fi traffic are transferred through the SDIO bus
to the module. The Bluetooth traffic uses the high-speed UART interface.
•SDIO-SDIO mode: Commands and data for the Wi-Fi and Bluetooth traffic are transferred through
the SDIO bus to the module.
DIP switch SW503 is used on the EVB to define the boot 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”).

resistors connected on module board.
VDD_SDIO is connected to the power supply connector (J105) and is used for supplying 3.3 V for
VBAT from the SDIO interface. The SDIO interface has 50 Ωimpedance. 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 them in case if
needed by the design.
3.6 Bluetooth host interface
The Bluetooth UART host interface of the JODY-W2 series module can be accessed either directly
through the UART pins on J305, or through the USB type-C connector J205 through a USB-to-UART
bridge (default).
A USB-to-UART bridge (FTDI FT231X) is included on the evaluation board to connect to the high speed
UART interface of the JODY-W2 series modules. VDD_USB3 from the USB connector is converted by
a DC-DC to 3.3 V and can be used for supplying VBAT from the USB interface. Place the jumper on
J400 to use Bluetooth through the USB type-C connector.
Figure 15: Jumper setting to use Bluetooth over USB
The 4-pin UART interface of the JODY-W2 series modules can be directly accessed through the
Bluetooth UART connector J305, as shown in Figure 16. To use the UART interface directly, remove
the jumper on J400 and connect the UART host interface to the respective module side pins and GND
on J305, as shown in Figure 16 and Table 9. The UART signals are powered by the VIO voltage domain.

3.7 Bluetooth audio interface
A MAX9860 16-bit audio codec for Bluetooth voice applications is provided on the JODY-W2 EVK and
connected to the PCM interface of the module. A 3.5 mm audio jack (J206) to connect a headset is
available on the bottom side of the EVK. The codec is operated with a master clock (MCLK) of
19.2 MHz. The MAX9860 audio codec is completely controlled through software using an I2C
interface. The codec responds to the I2C slave address 0x20 for all write commands and 0x21 for all
read operations.
Place jumpers J401 and J402 to enable the audio codec, as shown in Figure 17.
Figure 17: Enable audio codec option
The I2C interface of the audio codec is provided on connector J303 of the EVK as shown in Error!
