Arduino Uno R3 DIP IC High Quality Board

Arduino is a microcontroller Development Board with ATmega328p Microcontroller.

• The required minimum voltage is 5v.
• having 14 Digital GPIO pins and 6 analog pins.
• 5v and 3.3v power pins with 3 ground pins onboard.
• Another SMD microcontroller inbuilt for boot the Arduino main chip.
• there is also two voltage regulator one is for 5v and another is for 3.3v.
• for SPI protocol there is MISO, MOSI, SCK, and SS pin which is pin 12, pin 11, pin 13 and pin 10 respectively.
• for I2C protocol there are SCL and SDA pins above the pin 13 & Vref.
• serial communication by the pin Rx & Tx Which are given at pin 1  & pin 2.
• There are also some PWM pins on the board you can see all the detail in the given diagram.
