Explore the features and benefits BlueNRG-M2, STMicroelectronics’ ultra-low power programmable Bluetooth® Low Energy wireless SoC solution.
The BlueNRG-M2 is a Bluetooth® low energy system-on-chip application processor certified module, compliant with BT specifications v5.2 and BQE qualified. This module supports multiple roles simultaneously and can act at the same time as Bluetooth master and slave device. The BlueNRG-M2 includes the BlueNRG-2 system-on-chip, entire Bluetooth low energy stack and protocols embedded into module. This provides a complete RF platform in a tiny form factor. Radio, embedded antenna and high frequency oscillators are integrated to offer a certified solution to optimize the time-to-market of the final applications. The BlueNRG-M2 can be powered directly with a pair of AAA batteries or any power source from 1.7 to 3.6 V.
