MYB-Y6ULX is equipped with a SDIO WIFI module with offering SMA antenna connector.
The part number of WIFI chip is WM-N-BM-02 from USI. The WiFi module support
802.11b/g/n. The SDIO port of the module has been connected to the SD2 controller of
the processor. On board SMA type antenna interface, it can be used with WIFI antenna in
the development kit box.
It is important to note that as the eMMC and WIFI modules use the same MMC controller,
the eMMC version of the CPU module does not support this feature. In addition, The SDIO
pins are pulled down 47K to ground on the CPU module and multiplexed with the boot
configuration pins. User should pay attention to the initial state on those pins, to avoid
causing the boot failure, on base board design.
