Product specifications
LM931 BT4.1 Smart Mod,BLE,Onb Antenna with IC
The LM931 Bluetooth® low energy module is designed for use within embedded systems. It is implemented as a peripheral device within a product, while saving the developer valuable PCB space. The LM931 enables wireless communication with other nearby Bluetooth® low energy devices (e.g. iOS and Android) using a highly power efficient connection. The transmission output power ranges from 0 dBm to 9 dBm and can be configured to provide an extended battery life or a longer communication range.
This single core standalone module combines a Bluetooth® low energy radio using a Bluetooth® v4.1 stack, plus a microcontroller with 512 kB EEPROM for running the application. The LM931 incorporates 27 pin outs including UART and I2C for interfacing with a wide range of peripheral devices like sensors. It’s SMT side and bottom pads allow for easy manufacture and placement into your product. Application firmware and configuration settings can be preloaded to the module before supply.
LM offer bespoke integration into your product by supporting your developer. We can also assist in the development of new applications for the module. IoT Applications such as Serial over GATT, iBeacon™ and Key Fob (with RGB LED Controller) are available with the module’s LM53X development kits. The firmware is customisable to meet your requirements.
