Imfuneko Yezimpawu Zedijithali Ezisheshayo
Ukulandelelwa kwe-SDIO kufanele kube umzila wokulibaziseka we-isometric uziro onokubambezeleka okungu-50 Ω.
Pull-ups in the 10 kΩ to 100 kΩ range are required on the four DATA lines and the CMD line. This requirement must be met during all operating states either through the use of external pull-up resistors or  through proper programming of the SDIO host’s internal pull-ups.

Izimfuneko Zezimpawu Ezingasetshenzisiwe
If these signals are not used, no pull-up/down is necessary (floating) for

• WL/BT_HOST_WAKE
•  BT_DEV_WAKE
• WL_GPIO_*
• BT_PCM

I-Module Footprint Design
Refer to dimensions in the Type 1YN Datasheet . Idatha ye-DXF File ye-module footprint inikezwa nge webindawo.

Design Guide: VBAT/CBUCK Line
The guidelines are:

• Make the line from SR_VLX to VIN_LDO as short as possible. The 4.7uF capacitor should be as close to VIN_LDO as possible.
• If the main board is multilayer PCB type, it’s better to separate the GND place for this area on the top later, then connect it to the main GND thru the via hole on the lower layer.
• On VBAT line, 4.7uF bypass capacitor should be located as close to the module as possible.
