The BlueNRG-2 and BlueNRG-2N processors offer excellent RF performance, robustness and connection reliability. The
integrated high-efciency DC/DC converter enables ultra-low power gures with an enhanced sleep mode, extending battery
lifetime. The BlueNRG-2 and BlueNRG-2N come with a full-featured eco-system of tools, evaluation boards and software
development kits (SDKs). Suitable for 9-axis Sensor Fusion (MotionFX library), ADPCM audio compression (BlueVoice library),
and Bluetooth SIG Mesh-ready. The Navigator PC GUI allows users to quickly run examples and start developing new projects
out-of-the-box. BlueNRG-2 and BlueNRG-2N are part of ST’s 10-year longevity program.
