IMG iEB110

Ensigma Bluetooth Connectivity Family

Bluetooth Low Energy v5.2

The IMG iEB110 is a complete Bluetooth Low Energy v5.2 solution, including RF, controller software and Bluetooth Low Energy host stack, enabling product developer to create small form-factor, low power audio devices such as earbuds and hearing aids. IMG iEB110 supports advanced Bluetooth 5 features such as Angle of Arrival/Angle of Departure (AoA / AoD) allowing sub 1m location and tracking accuracy, LE long-range operation for extended indoor and outdoor coverage, and LE-2M PHY for higher throughput and reduced power consumption. With industry leading RF performance, IMG iEB110 delivers robust connectivity while extending the system battery life.
