H=1.0mm，W=1.0mm，D=0.254mm（Recommended） H=1.2mm，W=1.0mm，D=0.2mm（Recommended） H=1.6mm，W=1.0mm，D=0.2mm （Recommended） （Ask Lierda engineer for more design support） 4.2 Notice for base board layout Save enough clearance zone for antenna . Clearance refers to the space area in the projection area of the vertical plane of the antenna (both upper and lower areas should be considered). -
Page 12: Notices
4.3 Notices 1. Power Supply It is suggested supplying power to the module with DC regulated power supply. The ripple of power supply should as small as possible. Usually the ripple is less than 30 mV. Excessive ripple will lead to poor sensitivity and other connection abnormalities. At the same time, the transmitting signal of Bluetooth will be coupled into the interference signal, which will cause the radio frequency to exceed the Bluetooth specification, and even will result in failed connection and communication. -
