I2C is a two-wire communication protocol. These pins are used to send or receive data by the controller. MISO (Master Input Slave Output) and MOSI (Master Output Slave Input) are mainly incorporated for SPI communication between devices. It is used to develop communication between the controller and other peripheral devices like shift registers and sensors. Which serial peripheral interface communication protocol. These pins are mainly used to control the speed of the motor. These pins generate analog results with digital means. Out of 14 digital pins, 5 are used as PWM pins. These pins can receive any number of values in comparison to digital pins that only get two values HIGH or LOW. When they receive 0V they are in a LOW state and when they receive 5V they are in the HIGH state.Ħ analog pins are available on the board. Let’s get started.ġ4 digital pins are installed on the board which you can use as an input or output according to the requirement. In this section, we’ll detail the pin description of each pin incorporated on the board. This was all about the brief introduction to Arduino Uno WiFi Rev 2. The following figure shows the pinout diagram of Arduino Uno WiFi Rev 2. ICSP header is used to develop communication with other devices while pressing a reset button will reset the board and start the program from the initial stage. Other features include a power jack, USB connection, a reset button, and an ICSP header.The program you write for Arduino Uno will not work with Arduino Uno WiFi Rev 2. But the processor architecture of this Rev 2 board is different than the Arduino Uno since it incorporates a different chip. This board is an advanced version of Arduino Uno.Moreover, this board also incorporates Secure Element = ATECC608A and Radio module = u-blox NINA-W102 The operating voltage of this board is 5V.And the recommended input voltage ranges from 7V to 12V. The DC current for the 3.3V pin is 50 mA and the DC current per I/O pin is 20mA.While SRAM is used to manipulate and generate variables when it is activated. The EEPROM is a non-volatile memory which means it stays stored in the board even if power is removed from the board.The flash memory is 48KB that is mainly employed to store the sketch (Arduino program is called a sketch) while the EEPROM is 256bytes and SRAM is 6KB.There are total 14 digital I/O incorporated on the board out of which 5 are used as PWM pins and 6 analog pins are available on the board.The oscillator speed is 16MHz which is required for the synchronization of all internal functions.The safe and secure WiFi connection makes it an ideal pick for several industries including consumer electronics, automotive, agriculture, logging data, and small home automation projects.A brand new ECC608 crypto chip accelerator is included on the board to ensure a secure WiFi connection. ![]() ![]() Generally employed to develop fall sensors, step counters, door opening alarms. ![]()
