** It's recommended to insert 0 ohm resistors in WiFi SDIO/SPI<br />
pathes and keep them close to WG7310 module for test<br />
** The six traces from U1 ( module ) to Host must be<br />
treated like a bus. The bus length shall be as short<br />
as possible and every trace length must be the same as<br />
the others. Enough space above 1.5 time trace width or<br />
ground shielding between trace and trace will be benefit<br />
to make sure signal quality, especially for SDIO_CLK<br />
trace. Besides, please remember to keep them away from<br />
the other digital or analog signal traces. To add ground<br />
shielding to around the buses will be good.<br />
