Product Information

BLE121LR is a Bluetooth® Smart Long Range module targeted for Bluetooth Smart applications where the best possible RF performance and range are required. At +8 dBm TX power and -98 dBm sensitivity BLE121LR has best-in-class RF performance and can provide Bluetooth Smart connectivity up to 450 meters. BLE121LR integrates all features required for a Bluetooth Smart application: Bluetooth radio, software stack and GATT based profiles, and it can also host end user applications, which means no external microcontroller is required in size, price or power constrained devices.

BLE121LR Bluetooth Smart module also has flexible hardware interfaces to connect to different peripherals or sensors. Although BLE121LR Bluetooth Smart Long Range Module is targeted for applications requiring high RF performance, it is still has relatively low power consumption and can be powered using a standard 3 V coin cell battery.
