The JOY-iT R301T fingerprint sensor module is capable of image collection and algorithm calculation due to this integrated chip. Another remarkable function of the sensor is, that it can recognize the fingerprint in different conditions, for example humidity, light texture or changes of the skin. This offers a very wide range of possible applications to secure locks and doors among others. The chip can send data via UART, TTL serial and USB to the connected controller.

SmartScope is a compact 2-channel USB oscilloscope with a bandwidth of 30 MHz and a sampling rate of 2x 100 MSa/s. It is compatible with all major platforms, including Windows, macOS, Linux, and Android. The operation and display of measurement signals are done via smartphone, tablet, or PC. Additionally, a logic analyzer and a signal generator are integrated.
Even more, you can get mobile with it: take the SmartScope on the road, thanks to the single-cable connectivity. Everything is going to be intuitive: pointing, pinching and swiping finally replaces the clunky interfaces of old scopes.
With the SmartScope you develop your digital interfaces using the 100 MS/s logic analyzer. With this tool you can design any signal you want using Excel, then upload it to the built-in Arbitrary Waveform Generator (AWG). At the end capture the voltage at any point of your design at 100 million times each second.
The Software for the support of Windows / macOS / Linux / Android and Export formats (Excel .csv / Matlab .mat) are given.
