STMicroelectronics recently launched the all-in-one Bluetooth 4.2 module SPBTLE–1S designed to speed up prototyping and developments while reducing costs.
The module measures only 11,5 mm x 13,5 mm x 2 mm and includes the BlueNRG–1 SoC as well a power supply filter, the oscillators for the MCU, the baluns, the filters used for matching networks and reducing harmonics, and even the ceramic antennas.
The company released an all-in-one BLE solution in the past, the SPBTLE-RF, but it didn’t integrate a Cortex MCU, it was compatible with Bluetooth 4.1, and its transmit power was +4 dBm, whereas the new module is compatible with Bluetooth 4.2 and can achieve +5 dBm. Furthermore, the SPBTLE–1S has already passed the FCC, IC, CE, and SRCC certifications for the United States, Canada, the European Union and China respectively.
Its range of operating supply voltage from 1,7 V to 3,6 V means the same module accepts a wide variety of power sources, from AAA batteries to coin cells. The component is also compatible with numerous interfaces, such as UART, SPI or I²C.
The quickest and easiest way to start developments is to obtain the STEVAL-IDB007V1M evaluation board, which includes the SPBTLE–1S, a 3D digital accelerometer and 3D digital gyroscope (LSM6DS3), as well as a barometer that’s also a thermometer (LPS25HB). It has Arduino connectors to plug additional boards, a battery holder to test mobile application, and a USB port to very quickly load firmware or debug the system. All engineers have to do to get started is download the STSW-BLUENRG1-DK software pack, which includes a GUI, demonstration programs, drivers and source code.
