STmicroelectronics’ wireless IoT & wearable sensor development kit
‘SensorTile.box’ is a portable multi-sensor circuit board housed in a plastic box and developed by STMicroelectronics. It is equipped with a high-performance 32-bit ARM Cortex-M4 processor with DSP and FPU, and various sensor modules, such as accelerometer, gyroscope, temperature sensor, humidity sensor, atmospheric pressure sensor, microphone, and so on. SensorTile.box is ready to use with wireless IoT and Bluetooth connectivity that can easily be used with an iOS or Android compatible smartphone, regardless of the level of expertise of the users. SensorTile.box is shipped with a long-life battery and all the user has to do is connect the battery to the circuit to start using the box.
The SensorTile.box can be operated in three modes: Basic mode, Expert mode, and Pro mode. Basic mode is the easiest way of using the box since it is pre-loaded with demo apps and all the user has to do is choose the required apps and display or plot the measured data on a smartphone using an app called STE BLE Sensor. In Expert mode users can develop simple apps using a graphical wizard provided with the STE BLE Sensor. Pro mode is the most complex mode allowing users to develop programs and upload them to the SensorTile.box.
This book is an introduction to the SensorTile.box and includes the following:
Brief specifications of the SensorTile.box; description of how to install the STE BLE Sensor app on an iOS or Android compatible smartphone required to communicate with the box.
Operation of the SensorTile.box in Basic mode is described in detail by going through all of the pre-loaded demo apps, explaining how to run these apps through a smartphone.
An introduction to the Expert mode with many example apps developed and explained in detail enabling users to develop their own apps in this mode. Again, the STE BLE Sensor app is used on the smartphone to communicate with the SensorTile.box and to run the developed apps.
The book then describes in detail how to upload the sensor data to the cloud. This is an important topic since it allows the sensor measurements to be accessed from anywhere with an Internet connection, at any time.
Finally, Pro mode is described in detail where more experienced people can use the SensorTile.box to develop, debug, and test their own apps using the STM32 open development environment (STM32 ODE). The Chapter explains how to upload the developed firmware to the SensorTile.box using several methods. Additionally, the installation and use of the Unicleo-GUI package is described with reference to the SensorTile.box. This PC software package enables all of the SensorTile.box sensor measurements to be displayed or plotted in real time on the PC.

This pack contains the LCR45 Passive Component Impedance Meter, great for advanced hobbyists and professionals. It also contains the very popular DCA Pro (model DCA75), fantastic for component identification, pinout identification, detailed characteristic measurement and curve tracing on a PC. Complete with USB cable and software on a USB flash drive.
DCA75
Building on the continued success of Peak's existing component identification and analysis instruments, the DCA Pro brings an array of exciting new features for the hobbyist and professional alike.
The DCA Pro is an advanced new design that features a graphics display, USB communications, PC Software and an enhanced component identification library.
Automatic component type identification
Automatic pinout identification (connect any way round)
The DCA Pro supports all the components that the popular Peak Atlas DCA55 supports, but adds plenty more. Components supported include:
Transistors (including Darlingtons), Silicon and Germanium types. Measures gain, Vbe and leakage
MOSFETs, enhancement mode and depletion mode types. Measure on-threshold (at 5 mA) and approx transconductance (for span of 3-5 mA)

Stand-alone or with a PC
The instrument can be used stand-alone or connected to a PC. Either way, the DCA Pro will automatically identify the component type, identify the pinout and also measure a range of component parameters such as transistor gain, leakage, MOSFET and IGBT threshold voltages, pn characteristics and much more.
Curve Tracing
When connected to a PC using the supplied USB cable, a range of low current curve-tracing functions can be performed. Various graph types are available, with more to follow:
Bipolar transistor output characteristics, IC vs VCE
Bipolar transistor gain characteristics, HFE vs VCE
Bipolar transistor gain characteristics, HFE vs IC
MOSFET and IGBT output function, ID vs VDS
MOSFET and IGBT transfer function, ID vs VGS
JFET output function, ID vs VDS
JFET transfer function, ID vs VGS
Voltage regulator, VOUT vs VIN
Voltage regulator, IQ vs VIN.
PN junction I/V curves, forward and reverse options (for Zener diodes)
Curve tracing is performed using test parameters in the range of +/-12 V or +/-12 mA. All curve-tracing data can be instantly pasted into Excel for further graphing and analysis. PC Software is included with the DCA Pro on a Peak USB memory stick. Software designed for Windows 7 and higher (all 32 or 64 bit).
LCR45
A great handheld LCR analyzer that can measure the value of your passive component (inductor, capacitor or resistor) and also measure the detailed impedance in a number of modes. The LCR45 offers enhanced measurement resolution (better than 0.1 uH!) whilst also giving you continuous fluid measurements. Additionally, the test frequencies of DC, 1 kHz, 15 kHz and 200 kHz can be set to automatic or manual modes. Supplied with removable gold plated hook probes, battery and user guide.
