I.Package Information

※ The Yellow area at the top of module is 2.4G print PCB antenna, under this area, please make the PCB clean without copper and traces. Please let the antenna area leave far away from metal as possible as you can, usually, the antenna part of Bluetooth module should be placed at the edge of your PCBA.

J.Typical Application

Since Bluetooth 4.0(BLE) came out, the apple phones started from iPhone 4S could support BT4.0, the terminal developers can directly use BT4.0 for product development, and no longer requires complex apple MFI authorization and corresponding payment, therefore, it makes BT4.0 become the best choice of developing Bluetooth peripherals of iOS.

But for Android, especially the previous versions before Android 4.3, which don’t support BT4.0, but only support traditional Bluetooth SPP protocol. Hence the traditional Bluetooth developers have to use two kinds of solution for their terminal products: SPP module for Android, and BT4.0 module for iOS. It caused the rising cost accordingly and more difficult to use for customers.

ELET114A Bluetooth Dual‐Mode module developed by ElinkEtone, which can not only support BT4.0, but also support the classic BT3.0/2.1+EDR and

SPP protocol, it achieves the perfect compatibility of iOS(MAC), Android and

other operating system, so that bluetooth terminal developers can easily implement their products’ upgrade, and promote the intrinsic value.
