Slider click features a mechanical slide action potentiometer - a slider, which gives a nice feeling when actuating, along with 16 SMD LEDs, that can be used for any kind of visual feedback. The onboard high-resolution 22-bit ADC can detect even the smallest move, faithfully capturing the smoothness of the slider movement, while digitizing its position. The 16 onboard SMD LEDs can give a nice visual feedback of the slider position, but those LEDs can also be used for other purposes since they are not hardwired to the slider.

Slider click can be used to control various digital applications with an accurate and comfortable slider potentiometer, while the LEDs can be used to display the desired information in a form of a bar or a position. For example, Slider click can be used to control a quad digital potentiometer, such as the one that can be found on DIGIPOT 5 click, while displaying the position of the selected digital wiper on the LEDs.

DIGI POT 4 click is a digitally controlled dual potentiometer, with the resistance of 10K?. It has a 10bit resolution which allows for a very smooth linear wiper positioning through 1024 steps. Digital wiper position can be controlled via SPI interface. DIGI POT 4 click also features a non-volatile durable EEPROM memory for storing the wiper position, which means that the device can restore its last position after the power on - just like its mechanical counterpart.

The main advantage of the digital potentiometers over the mechanical ones is that they can never wear out. The wiper position can be precisely programmed, and the wiper contact with the resistive coating can never be compromised by the influence of the dirt or moisture. Due to its low THD and good bandwidth, it can be used for digital volume control or a precise gain and offset adjustment. It can also be used as the LCD digital contrast control, and generally - whenever a precise dual digital voltage divider application is required.

ATA663254 click is a fully integrated LIN transceiver device with an integrated 5V LDO voltage regulator. The combination of voltage regulator and bus transceiver makes it possible to develop simple but powerful slave nodes in LIN bus systems.

The digital wiper position can be controlled via the SPI interface. DIGI POT 5 click features a durable EEPROM non-volatile (NV) memory for storing the wiper position. The content of the wiper register memory located in the NV memory is copied to the actual wiper registers after the power-on or reset state, so the device acts similar to its mechanical counterpart, recalling its last used wiper position after being powered on. The device also features the WiperLock™ technology, which effectively locks the wiper position in place.

DIGI POT 5 click has a multitude of practical uses in electronic circuits. The most popular uses include precision calibration of set point thresholds, sensor trimming, LCD contrast adjustment, audio attenuation, an adjustable gain for amplifiers and offset trimming. DIGI POT 5 click can be used to replace the common mechanical trim pot, in a wide range of different applications where the operating voltage stays within the limits.

RS232 Isolator click is a fully isolated dual transceiver click, used to provide secure and easy UART to RS232 conversion, with the galvanic isolation. The digital input and output signals are transmitted across the isolation barrier by utilizing the Analog Devices proprietary iCoupler® technology - IC scale transformer windings couple the digital signals magnetically, from one side of the barrier to the other, providing the galvanic isolation and transfer rates up to 460Kbps.

RS232 Isolator click can be used for galvanic isolation of RS232 signals, whenever there is a need for that kind of isolation - operating in harsh environments where electrostatic discharges (ESD) can occur, when the RS232 cable is plugged in and out frequently, and generally - wherever the sensitive part of the RS232 controller logic circuitry needs to be protected.

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.

BroadR-Reach® point-to-point Ethernet PHY technology was developed by Broadcom Limited. BroadR-Reach® technology is a robust Ethernet physical layer interface, designed for use in noisy environments and harsh conditions, such as in industrial networking applications. This technology allows multiple systems to simultaneously access information over the unshielded single twisted pair cable, reducing connectivity costs and cabling weight. As such, it offers a great alternative to older, rather limited standards used so far, and enables faster data rates to be transferred over the existing cable networks.

PIXI™ click is equipped with MAX11300 IC from Maxim Integrated, which features Maxim Integrated's versatile, proprietary PIXI™ technology - it is the industry's first configurable 20-channel mixed-signal data converter. Besides the 12bit multichannel SAR ADC and buffered DAC, it also features one internal and two external temperature sensors for tracking the junction and the environmental temperatures. Adjacent pairs of ports can be configured as logic-level translators for open-drain devices or analog switches. Each port is individually configurable with up to four selectable voltage ranges within -10 V to +10 V.

PIXI™ ports provide highly flexible hardware configuration for 12-bit mixed-signal applications.

Vibro Motor click features a compact size Eccentric Rotating Mass (ERM) motor, labeled as C1026B002F. This type of motor is often used for haptic feedback on many small handheld devices, such as the cellphones, pagers, RFID scanners and similar devices. This motor contains a small eccentric weight on its rotor, so while rotating it also produces vibration effect. This kind of motors is sometimes referred to as coin motors, due to its shape.

Besides the vibration motor, the click is also equipped with the DMG3420U, a small MOSFET, which is used to drive the motor. The Vibro Motor click is an ideal solution for adding a simple, one pin driven haptic feedback on any design.

A fan is a simple device that creates a flow within some fluid - such as the air, causing the heat accumulated in one section of the fluid to be moved away from the heat source, effectively cooling the affected area. The faster the fan rotates, the faster the fluid moves. This movement causes an audible noise which is one of the most obvious reasons why the fan speed control is needed, especially when the fan is used to cool down electronic components, such as the personal computer.

Fan 3 click is the perfect choice for speed control and it can operate in seven discrete speed steps. Unlike the PWM regulation which can sometimes cause the infamous coil whining effect on some types of fans, this click board outputs the selected voltage via the MIC29152 voltage regulator from Microchip, driven through the MIC74 - a serial to parallel I/O expander and a fan controller from the same company, keeping it constant at the output. Fan 3 click works with 12V to 25V on its input connector and can be used whenever a noiseless solution with a variable fan speed is needed, for example - cooling of electronic components with the minimal possible noise produced.
