1Kit description
The JODY-W2 series are 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].

3.2 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 20. To use external antennas, connect the cables to another
pair of U.F 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 sections 4.6 and 4.9 for detailed instructions.
6. Install the necessary driver software for JODY-W2 series modules, as described in the system
integration manual [2].
3.3 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.
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.
3.4 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 all the signals. Using
3.3 V the SDIO interface operates in High Speed (HS) mode. Figure 3 shows how the level shifter and
EVK are connected. For more information about level shifters see the 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.

3.5 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. Refer to section 4.9.2 for
information on how to use the Bluetooth UART on the evaluation board.
These resistors must be connected
in vertical positions.

jumpers are shown with red lines terminated with round edges.
Figure 8: Jumper convention
4.3 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.

4.5 SDIO Interface
The boards can be connected through a micro or full-size 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 14.
Figure 14: SDIO interface connector
All signals except VDD_SDIO are directly connected to the JODY-W2 module through 22 Ωseries
resistors connected on module board.

C1 - Public
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 are not installed on the EVK because in-general host boards have them, but
the carrier board has the provision to install them in case if needed by the design.
4.6 Bluetooth UART interface
To use UART for communication with Bluetooth, choose either the type-C USB connector provided
with the kit or UART pins. A type-C USB connector is used for Bluetooth communication with the
JODY-W2 series modules.
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_USB from the USB connector is converted by
a DC-DC to 3.3 V and connected to the power supply connector (J104) for supplying VBAT from the
USB interface.
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 15. To use the UART interface, remove the J400
jumpers and connect the UART host interface to the respective module side pins on J305, as shown
in and Table 8. Signal ground can be connected to one of the available GND pins on J303 as shown in
Figure 17. The UART signals are powered by the VIO voltage domain.

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.
