MCP73871 click is a fully integrated solution for system power delivery and Li-Po/Li-Ion battery charge management. The click features many Li-Po/Li-Ion battery charging optimizations, used to maximize the battery life. Some of the MCP73871 click features include constant current and voltage charging algorithms, overvoltage protection, automatic end of charge control, automatic recharge feature, preconditioning for depleted cells and thermal management.

All these features, coupled with the ability to simultaneously power up the system load and charge the connected battery, make this click a perfect solution for powering up many different battery-operated builds and projects, which use a rechargeable Li-Po/Li-Ion battery, but can also switch to an external power source.

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.

MIC33153 click is a DC-DC adjustable step-down (buck) converter that is designed to deliver a substantial amount of current to very demanding loads, with the voltage output up to 3.5V. The ultra-fast transient response and the ripple free output voltage are some of the main features of this DC-DC step-down converter. The proprietary HyperLight Load™ technology allows very efficient step-down conversion even for very light loads.

This adjustable DC-DC step-down converter click board™ has a very specific field of applications in which it gives the best results. Due to its ripple free voltage output and very high conversion efficiency, it is designed to be used as the power supply for the various portable GPS devices, mobile handsets, portable media and mp3 players, wireless LAN cards and similar applications that demand very clean power supply and high step down DC-DC conversion efficiency factor.

Moisture click is a Click board™ that can be used to easily detect a moisture level of the skin, by simply touching the sensitive surface of the PCB. The Click board™ is equipped with the printed copper trace sensor, which is sampled by the accurate FDC2112 IC, a 12bit capacitance to digital (FDC) converter, which employs innovative noise and EMI resistant capacitance measuring techniques. This sensor allows the Click board™ to measure the skin moisture by measuring its capacitance, which changes depending on the skin moisture level (hydration state of the outer epidermis).
