Description 

Outline  

Full-size SD/SDIO 
adapter 

Full-size SD to ZIF adapter for Wi-Fi SDIO 
host communication. The adapter is 
compatible with host sockets designed for 
full-size SD cards and supporting SDIO. 
Flat cable: Molex 15166-0167, 102.00 mm 
cable length, 16x circuits 

 

Type-C USB cable 

Type-C USB cable for Bluetooth host 
communication over UART connected via 
on-board (EVB) FTDI USB-to-UART bridge. 

 

External antennas 

2 x Dual band Wi-Fi/Bluetooth antenna, 
Linx Technologies ANT-DB1-RAF-SMA 
(EVK-MAYA-W271)

Software 

MAYA-W2 series modules are based on the NXP IW611/IW612 chipsets. The open-source drivers and 
firmware required to operate MAYA-W2 series modules are developed by NXP and are already 
integrated into the Linux and Android BSP for the NXP i.MX application processors 

[3]

  and the 

MCUXpresso SDK for NXP MCU device

[5]

. 

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 
under NXP licensing terms. As open-source software, the drivers can be integrated or ported to other 
non-NXP based host platforms.  

1.3.1

 

Open-source Linux/Android drivers 

The latest version of the Linux/Android 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/

 

 

Use the repository branches matching to the latest Linux BSP release version. At the time of 
this document publication, this is release 6.1.36_2.1.0. 

Yocto recipes for the driver and firmware (nxp-wlan-sdk, kernel-module-nxp-wlan, firmware-nxp-wifi) 
are included in the NX

meta-imx

 an

meta-freescale

 layers. 

Bluetooth uses the 

hci_uart

 or 

btnxpuart

 driver from the Linux kernel and BlueZ host stack. The 

OpenThread stack (provided by Google Nest Team) and Matter (Project CHIP) are used for 802.15.4 
based applications. NXP provides an OpenThread binary that can be run as a Thread application, or it 
can be built from source code. 

For further information about initialization and configuration of the Wi-Fi and Bluetooth features, see 
also the MAYA-W2 series system integration manua
