The SensiEDGE module features a suite of sensors, Bluetooth connectivity, and a microcontroller in one of the world’s tiniest system-on-board solutions. The Bluetooth- and FCC/IC-certified module is a combination of four ST Nucleo development boards, with the heart of the module containing the STM32L476RG Arm Cortex-M4 32-bit microcontroller for running the software.
The flexibility of the module offers the opportunity to use it in a design as-is, or switching it out for individual components once volumes increase and the design goes into full-scale production — all without significant rework.
The module also features a host of configurable hardware options that are ideal for IoT applications, including a low-power module for Bluetooth 4.1, a stereo digital microphone, and 4 Mbits of SPI flash.
It offers a variety of onboard sensors for tracking applications, including a 3-axis accelerometer, gyroscope and magnetometer. Ideal for environmental applications, and it features a relative humidity with temperature sensor, pressure sensor, digital RGB/IR and ambient light sensor with color detection, plus a digital microphone.
Additionally, dedicated apps and a software development kit (SDK) for the iOS and Android enable communication with the SensiBLE module to begin reading sensor values; unique customer apps can also be developed.
The SensiEDGE SensiBLE IoT module is powered using a coin cell battery (which can be extended to a rechargeable battery via minimal changes), mini USB or external power. It is supported by a SensiBLE Development Kit, which features an integrated debugger, Arduino-compatible headers, and PC connectivity. SensiBLE is also fully compatible with ST’s STM32 Nucleo and X-Nucleo ecosystem for rapid development and deployment.
Target IoT applications include battery-powered sensor devices, wearables, smart appliances, medical and fitness trackers, home automation, consumer electronics, retail beacons, and asset trackers.
