7-segment LED display is the most commonly used type of display to represent changing numerical values. The principle is very simple - seven LED segments are positioned in a certain shape and by turning specific segments on or off, the shape that resembles a specific number is lit. This method of displaying numbers was first used in the beginning of the 20th century, but after the invention of the LED in '70, it is the most commonly used method to display numbers. It utilizes a fairly simple and cheap design with the numbers clearly visible. Be it a clock on the nightstand, a billboard at the airport, a gauge on some machine, a panel on some instrument or a display on the pump at the gas station - the numbers will be always easy to see and read, even in the dark.

UT-S 7 SEG R click uses two SMD ultra-thin DSM7UA20101 7-SEG LED displays, made with the patented technology that delivers thickness of only 2.1 mm. These displays are driven by the MAX6969, a constant current LED integrated driver from Maxim Integrated, which uses the SPI serial interface for communication and delivers steady and constant power source for the LED segments.

LED Flash 2 click is a powerful flash/torch click, featuring the MIC2870 from Microchip, a high-efficiency flash LED driver, optimized for driving one or two high-brightness camera flash LEDs. The MIC2870 IC can drive one high brightness LED up to 1.5A or two high brightness LEDs, up to 750mA each. Two high brightness LEDs are already mounted on the Led Flash 2 click, so the click board is ready to be used right away.

LED Flash 2 click provides two modes of operation - the Torch mode and the Flash mode. While working in Torch mode, the output current is adjusted so that the continuous operation of the LEDs is provided. When it is set to work in the Flash mode, the LED current is maximized and while giving a powerful light, it can not work for prolonged periods. The Torch mode will turn the click board™ into a simple handheld torchlight, while the Flash mode is good for using the LEDs as the camera flash, providing good images in various low light situations.

MIC24055 click is the buck regulator that can deliver continuous output current up to 8A and can step down voltages from up to 19V which makes this click board easy to use with many power sources commonly available. The amount of current it can deliver and the steady, ripple-free regulated voltage, make this click board a perfect choice for powering up devices which require high current, regulated power supply, such as servers and workstations, routers, telecom equipment and every other electronic device with similar power demands.

MIC24055 click is equipped with the MIC24055, high-efficiency buck regulator from Microchip. This IC can work with the wide range of input voltages, from 4.5V up to 19V. The regulated voltage at the output can be set from 1V to 4.8V by the means of the feedback (FB) pin and the second chip on board - MCP4921, a single channel 12-bit DAC by Microchip, equipped with the SPI interface. By programming the output of this DAC through the SPI interface routed to the mikroBUS socket pins, it is possible to easily set up the output voltage of the buck regulator. MikroElektronika libraries make it possible to perform this task easily, as seen in the example application.

RTD click is based on MAX31865 resistance to digital converter from Maxim Integrated, optimized for platinum resistance temperature detectors, or RTD. The click uses the PT100 type platinum probe for temperature measurement. There are four screw terminals on the board, so different PT100 probe types can be used with this design. This click board™ can work with 2, 3 or 4-wire PT100 probe types.

RTD probes are commonly used to measure a range of temperatures between -200°C and 500°C, but the exact value depends on the specific probes used. Features like the 15bit ADC resolution, input terminals overvoltage protection up to ±45V, fault detection, fast response time of 21mS and the SPI interface, make the RTD click an ideal solution when it comes to precise measuring of extremely high and low temperatures.

Secure 4 click includes the ATECC608A, a secure CryptoAuthentication™ device from Microchip, which is equipped with an EEPROM array which can be used for storing of up to 16 keys, certificates, consumption logging, security configurations and other types of secure data. Access to the various sections of memory can be restricted in several different ways and then the configuration can be locked permanently, to prevent changes.

The ATECC608A equipped on this click board™, supports the I2C interface with a flexible command set, that allows use in various security applications, including Network/IoT Node Endpoint Security, Secure Boot, Small Message Encryption, Key Generation for Software Download, Ecosystem control, Anti Counterfeiting and similar.
