The Arduino Nano is equipped with 30 male I/O headers, in a DIP-30-like configuration, which can be programmed using the Arduino Software integrated development environment (IDE), which is common to all Arduino boards and running both online and offline. The board can be powered through a type-B mini-USB cable or from a 9 V battery. [2]
ATmega328 is commonly used in many projects and autonomous systems where a simple, low-powered, low-cost micro-controller is needed. Perhaps the most common implementation of this chip is on the popular Arduino development platform, namely the Arduino Uno, Arduino Pro Mini [4] and Arduino Nano models.

An example SPI with a master and three slave select lines. Note that all four chips share the SCLK, MISO, and MOSI lines but each slave has its own slave select. Chip select (CS) or slave select (SS) is the name of a control line in digital electronics used to select one (or a set) of integrated circuits (commonly called "chips") out of several connected to the same computer bus, usually ...
A Queued Serial Peripheral Interface (QSPI; different to but has same abbreviation as Quad SPI described in § Quad SPI) is a type of SPI controller that uses a data queue to transfer data across an SPI bus. [19] It has a wrap-around mode allowing continuous transfers to and from the queue with only intermittent attention from the CPU.
A finite state machine showing the processor transactions for the MOSI protocol. In MOSI protocol, each cache has the following requests: PrRd - Processor request to read a cache block. PrWr - Processor request to write into a cache block. BusRd - Snooped request indicating that there is a read request to a cache block made by another processor.
