  The Arduino mini i2c is a compact microcontroller board based on the Arduino platform. It is an open-source hardware project. It features a small form factor with 14 digital input/output pins, 6 analog inputs, a mini USB port for programming, and a reset button. It uses an ATmega328 or ATmega 168 chip as the core microcontroller, which runs at 16 MHz. It also has 32 KB flash memory for storing programs and 2 KB RAM for data storage. The board does not have a built-in USB port like the Arduino Uno, which makes it more compact. Hence, it requires an external USB-to-Serial adapter for programming.

• I2C Interface (TWI)

  I2C (Inter-Integrated Circuit) communication is a two-wire protocol widely used in embedded systems. It allows multiple components to be connected and communicate with each other using only two lines of communication: one for data (SDA) and one for clock (SCL). The Arduino mini board uses the Wire library to simplify I2C communication, enabling users to easily integrate and control I2C-compatible sensors, displays, and other devices within their projects.

• Run on 5V

  The Arduino Mini board is powered by a 5V supply through either a USB connection or an external power source. It can also be powered through the onboard voltage regulator, which allows the board to operate within a range of 6 to 20 volts. However, it is recommended to use 7 to 12 volts for optimal performance and to avoid damage.
