ST Microelectronics – SPBTLE-1S

The SPBTLE-1S is a Bluetooth® low Energy System-on-Chip application processor certified module, compliant with BT specifications v4.2 and BQE qualified. The SPBTLE-1S module supports multiple roles simultaneously and can act at the same time as Bluetooth Smart master and slave device.

The SPBTLE-1S is based on BlueNRG-1 system-on-chip and entire Bluetooth Low Energy stack and protocols are embedded into module.

The SPBTLE-1S module 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 SPBTLE-1S can be powered directly with a pair of AAA batteries or any power source from 1.7 to 3.6 V.
