LM931-0552

Description

LM931-0552, Bluetooth Smart Module 4.1 BLE with IC Antenna

The LM931 Bluetooth Smart Module 4.1 Bluetooth Low Energy is designed for use within new and existing embedded systems. It is implemented as a peripheral device within products such as monitors, meters and printers, while saving the developer valuable PCB space. The LM931 enables you to wirelessly communicate with other nearby Bluetooth Smart devices (e.g. iOS and Android) using a highly power-efficient Bluetooth Low Energy 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 range.

This single core standalone module combines a Bluetooth Low Energy Radio using a Bluetooth 4.1 stack, plus a microcontroller with 512 kB EEPROM for running the applications. 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.
