Development Tools Selector - DTS

DigiVref click is a very precise voltage reference Click board™, which allows one of four different voltage values to be selected over the SPI interface. Once the selection is done, the voltage reference stays fixed, even when the SPI interface is completely disconnected. The voltage reference is buffered by an operational amplifier, and thus it is very stable. Thanks to the MCP1541, a high precision voltage reference IC, and high thermal stability used resistors, the output voltage remains highly regulated, keeping the thermal drift very low. It can be used whenever a precise voltage reference is required. DigiVref click is supported by a mikroSDK compliant library, which includes functions that simplify software development. This Click board™ comes as a fully tested product, ready to be used on a system equipped with the mikroBUS™ socket.

GSR click can be used to measure the electrodermal activity (EDA) of the human body, also known as the galvanic skin response (GSR). EDA is actually the property of the human body that causes continuous variation in the electrical characteristics of the skin. EDA monitoring is usually combined with the monitoring of the heart rate, respiratory rate, and blood pressure, giving a complete insight into some of the parameters of the autonomous nervous systems of the human body. EDA measurement is a component of modern polygraph devices, often used as lie detectors. Recent research reveals that there is more to EDA than it seems, so the studies continue in that direction. GSR click is ideally suited to be used as the research and experimenting tool, as well as for building useful test applications based on the EDA response - such as the polygraphs.
