Table 2 shows the various components included in the EVK-JODY-W2. Part Description Outline Evaluation board (EVB) Evaluation board for JODY-W263 series modules.
Page 6 EVK-JODY-W2 - User guide 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 and the MCUXpresso SDK for NXP MCU devices [8].
Page 7 ºC Ripple Noise Peak-to-peak voltage ripple on all supply lines. Table 3: EVK-JODY-W2 operating conditions ☞ The signal voltage for the SDIO interface of the JODY-W2 series module is powered from the 1V8 supply. A level shifter is required to operate the module in default Speed and High-Speed modes at 3.3 V signal voltage.

Page 10 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.
Page 11 EVK-JODY-W2 - User guide These resistors must be connected in vertical positions. Figure 5: Resistor modification to enable host connection through an adapter 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.
Page 12 EVK-JODY-W2. 3.1 Block diagram EVK-JODY-W2 design is organized between the module board and carrier board. The carrier board includes all the necessary peripherals and connectors. It also includes a slot for mounting the module board. The module board holds the JODY-W2 module.
Page 13 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.

Page 18 EVK-JODY-W2 - User guide 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.
Page 19 EVK-JODY-W2 - User guide Figure 14: SDIO interface connector All signals except VDD_SDIO are directly connected to the JODY-W2 module through 22 Ω series 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.
