Bluetooth® low energy Module v4.1 with IC Antenna – LM931

Bluetooth® low energy Module v4.1 with IC Antenna – LM931 can be used within a wide range of embedded systems including Beacons, key fobs and sensors. While saving the developer critical physical space. The LM931 enables you to wirelessly communicate with other nearby Bluetooth® low energy devices (e.g. iPhones and Android devices). Using a highly power efficient Bluetooth® low energy connection.

This standalone module allows the developer to connect peripheral devices and runs the Bluetooth® low energy user application, without using an external MCU. LM offer Bluetooth® low energy application support to the developer and can create new user applications for the module. We also offer Bluetooth® low energy demo applications, which can be customised to your specification.

Your developed user application and settings can be preloaded to the LM931, simplifying the manufacturing and testing process. Its SMT side and bottom pads allows for easy integrations into your embedded system.
