Getting Started with NXP-based Wireless Modules on i.MX 8M Quad EVK Running Linux OS
3.4 88W8987-based Azurewave AW-CM358-uSD module
Azurewave provides a micro-SD card interface adapter (uSD-1212) with AW-CM358SM
module that is compatible with the i.MX 8M Quad EVK. The AW-CM358-uSD supports
Wi-Fi through a uSD device interface that conforms to the industry SDIO Full-Speed
card specification and allows a host controller using the SDIO bus protocol to access
the Wireless SoC device. The AW-CM358-uSD acts as the device on the SDIO bus, and
features the following:
• SDIO 3.0 standard
• On-chip memory used for CIS
• Supports 1-bit SDIO and 4-bit SDIO transfer modes
• Special interrupt register for information exchange
3.4.1 Recommended antenna part
MAG.LAYERS: MSA-4008-25GC1-A2
3.4.2 Supported I/O signal level
• SDIO (3.0/2.0) supports 1.8V for I/O signal
3.4.3 Supported RF standard
I/O voltage level Wi-Fi Bluetooth
AW-CM358-uSD 1x1 Wi-Fi 5 (2.4/5 GHz) 5.0
Table 5. Supported RF standard
3.4.4 Supported Wi-Fi features
AW-CM358-uSD and AW-CM358MA modules share the same Wi-Fi feature set. Refer to
Azurewave AW-CM358SM Datasheet.
Note: Azurewave AW-CM358-uSD supports both Wi-Fi and Bluetooth RF standards. But
as i.MX 8M Quad EVK does not include the FFC connector for Bluetooth interface, only
Wi-Fi is supported for i.MX 8M Quad platform with AW-CM358-uSD module combination.
