also easily support development of monitoring and tracking applications as standalone sensor node connected to

iOS/Android smartphone applications.

The SensorTile comes in a very small square shape 13.5 x 13.5 mm. All the electronic components are on the top

side of the pcb, while the bottom side has a small connector through which it is possible to easily plug and unplug

it from a motherboard. The connector pinout is also replicated on 18 pcb pads that render the SensorTile a

solderable system on module as well.

The module comes with pre-loaded FP-SNS-ALLMEMS1 (former BLUEMICROSYSTEM2) software that initializes

all the sensors and the Bluetooth low energy radio. The STBLESensor app, available free of charge on the

respective Google and Apple stores, is the easiest and fastest way to start using the SensorTile board and to

experience a real activity monitoring system.

The SensorTile firmware package STSW-STLKT01, built on the STM32Cube software technology, includes all the

low level drivers to manage the on-board devices and system-level interfaces. It has been designed in order to be

easily extended and personalized as starting point for development and customization of new dedicated

applications.

All the firmware packages are freely available on www.st.com.

The Bluetooth radio power output is set by default at 0 dBm. The FCC and IC certifications refer to this operating

value. The power output can be changed up to 8 dBm by reprogramming the device firmware, but the change of

this operating value will require an update of the FCC and IC certifications, with additional radio emission tests to

be performed.
