Nano Power Click Board
The Nano Power Click BoardÖ is a boost (step-up) DC-DC converter click with extremely high efficiency and very low input voltage, aimed at the low power IoT market and battery-powered sensors and other devices. The input voltage can be very low: the conversion will start for voltages down to 0.95V, providing 5V to the connected load. Once started, the input voltage can drop as low as the 0.4V, depending on the connected load. The onboard DC-DC converter IC uses the pulse frequency modulation control scheme (PFM), that allows high efficiency and low power consumption for a wide range of output currents.

Charger Click Board
The Charger click is an add-on board that comes integrated with two chips, one is a battery charger controller, and the other one is a battery charge monitor. The smaller chip MCP73831 is a miniature single-cell, advanced linear charge management controller that is commonly used is space-conscious and budgeted applications. This fully integrated Li-ion, Li-polymer charge management controller works with a programmable charge current from 15 mA to 500 mA. The larger chip DS2438 is a smart battery monitor, commonly used in portable computers, cell phones, consumer electronics, handheld instrumentation, etc. The board also features an on-board battery connector to facilitate connection. Charger click uses the unique 1-Wire interface, which requires only one port pin, for communication with the target microcontroller. The DS2438 has a unique silicon serial number, which allows several units to work on the same 1-Wire bus.
This permits multiple battery packs to be charged or used in the system simultaneously. It is designed to operate using a 5V power supply source.
Buck Click Board
The BUCK Click Board is a buck switching regulator that accepts a wide input voltage range of up to 40V and steps it down to 3.3V or 5V. The click carries the LT3976 40V, 5A, 2MHz step-down switching regulator with 3.3?A quiescent current.
BUCK click communicates with the target microcontroller over the following pins on the MikroBUS line: PWM, INT, RS, CS.
Boost 4 Click Board
The Boost 4 Click Board carries the TPS61230A, a high efficiency fully integrated synchronous boost converter from Texas Instruments. The click is designed to run on a 3.3V power supply.
Boost 4 click drives the target chip through the digi pot, which has SPI communication with the microcontroller on the system.
