Supporting Documentions:
Reference Schematic:
The most recent schematic , bill of materil ,and layout file are available from the WLINK
TECHNOLOGY LTD.. Contact your WLINK representative for details.
Layout Considerations:
The BT30MD-A30P module is placed at the location where the antenna is away from the
power supply(i.e.,BT1 Battery contacts)and any digital signal traces.. The antenna
keep-out area which is 5mm around the parameter of the module region is shown in the
red dotted box. PCB material and signal traces should not be placed within the antenna
keep-out area to assure optimum antenna performance.
