As the full-time experience specialist of ST's latest high-rise development kit (in fact, there is no such position), Xiaobian has gone through thousands of sails, there is a Bluetooth micro-sensing system with transformers direct vision, wearable products for lazy cancer late designer STEVAL-WESU1, Bluetooth and voice, you are the wind, I am Sand's Bluevoice... But when I saw this small development board, Xiaobian was still shocked and deeply attracted...
SensorTIle is a complete development kit that includes MCU, Bluetooth and a variety of sensors, and perfectly reflects what is concentrated is the essence, the core board size is only 1.35cmx1.35cm, such as the size of the fingertips, but it contains amazing The power of the wild...
SensorTIle development kit The kit contains the following sections:
STLCS01V1: SensorTIle core board
Thanks to the extremely small package characteristics of STMicroelectronics products, we integrate key components such as MCU, various sensors, Bluetooth low energy and MEMS microphones on such a small development board.
The main components include:
STM32L476 – 32bit Low Power CortexM4F MCU
LSM6DSM – iNEMO Inertial Module: 3D accelerometer and 3D gyroscope
LSM303AGR – High precision electronic compass, ultra low power 3D accelerometer and 3D magnetometer
LPS22HB – MEMS Barometric Pressure Sensor
MP34DT04 – 64dB SNR Digital MEMS Microphone
BlueNRG-MS – Bluetooth Low Energy Network Processor
BALF-NRG-01D3 – 50 Ω balun
External Interface: UART, SPI, SAI, I2C, DFSDM, USB OTG, ADC, GPIOs
All electronic components are concentrated on the front of the PCB, and the reverse side is plugged/welded to facilitate connection with the motherboard.
The STLCS01V1 is a highly integrated reference design prototype and pre-burned the BlueMicrosystem2 software package to initialize all sensors and Bluetooth BLE. With the ST BlueMS APP, you can start the SensorTIle experience journey quickly and easily.
SensorTile's firmware package STSW-STLKT01 is based on STM32Cube software technology, integrates all devices and interface drivers, and is easy to expand. It is very suitable for personalized development of new applications. All firmware packages are available free of charge.
2. STLCR01V1: SensorTile external board
The main components include:
STBC08PMR – 800mA linear charging chip
HTS221 - Temperature and Humidity Sensor
LDK120M-R – 200mA Low Noise LDO
STC3115 – Fuel Gauge
Micro-USB connector
Micro-SD card slot
SWD interface for easy debugging and programming
include:
SensorTile core board connection pin
Arduino connector for connection to the STM32 Nucleo development board
16Bit Low Power Stereo Audio DAC
SWD connector
In addition, the kit is equipped with a lithium battery, a programming cable and a protective case to meet various development scenarios.
Below, let's see what this magical little essence can do!
Turn on Bluetooth on your phone and open APP ST BlueMS
Click Start discovering to find Bluetooth devices
Once you have successfully connected, you can see the features displayed in the menu bar, such as:
Temperature, humidity and pressure real-time data
Real-time action following in the form of a dice
Various sensor data display and output
Motion recognition and carrying position recognition
Specific behavioral recognition, including tilting, picking up and shaking
Cute lighting function is also available ^^
Touch the light indicator on the phone screen to illuminate the small indicator light on the SensorTile
