General Description
The EW-MOD02 Module, is Bluetooth® Low Energy module based on world’s lowest power DA14531 SoC.
The module offers a unique combination of the lowest power and the integration of all external components including
antenna at a very affordable price.
The module is designed to enable the use of Bluetooth® Low Energy in applications where Bluetooth® Low Energy could
not be used until now because of cost or complexity. The bigger picture is to drive Bluetooth® Low Energy technology into
every application, turning every product into a connected IoT node to drive the next 1 billion IoT devices in the market.
The EW-MOD02 Module is supported by software that is easy to work with. This lowers the threshold to use Bluetooth®
Low Energy technology and significantly speeds up the design time.
