STMicroelectronics' SPBTLE-1S ready-to-use Bluetooth Low Energy (BLE) module integrates all the components needed to complete the radio subsystem.

Designed to help product innovators streamline the prototyping and development of connected smart objects, the 11.5x13.5mm BLE module integrates ST’s proven BlueNRG-1 application-processor SoC and balun, high-frequency oscillators, and a chip antenna among others. 
Developers can use this module to bypass hardware-design and RF-circuit layout challenges. The SPBTLE-1S is BQE-approved, and FCC, IC, and CE-RED (Radio Equipment Directive) certified to simplify end-product approval for North America and EU markets. ST’s Bluetooth 4.2 certified BLE protocol stack is included, and the supporting Software-Development Kit (SDK) contains a wide range of Bluetooth profiles and sample application code. 
The module comes with a wide supply-voltage range of 1.7V-3.6V, making it suitable for small, battery-operated objects powered by various types of sources such as a primary button cell or rechargeable Li-ion battery. High RF output power of +5dBm and good receiver sensitivity help to maximize communication range and reliability. 
The BlueNRG-1 SoC at the heart of the SPBTLE-1S implements the complete BLE physical layer (PHY), link layer, and network/application-processing engine comprising a low-power ARM Cortex-M0 core with 160KB Flash, 24KB RAM with data retention, and a security co-processor. The SoC also implements smart power management, with a DC/DC converter capable of powering the SPBTLE-1S module to ensure optimum energy efficiency. Users can leverage an extensive set of interfaces, including a UART, two I²C ports, SPI port, single-wire debug, and 14 GPIOs, as well as peripherals including two multifunction timers, a 10-bit ADC, watchdog timer and real-time clock, a DMA controller, and a PDM stream processor interface, which is ideal for developing voice-controlled applications.
