It has 14 digital input output pins of which 6 may be employed as pwm outputs 6 analog inputs a 16 mhz crystal oscillator a usb connection a power jack an icsp header along with a reset button. Arduino uno pinout pin diagram specifications and features in detail the arduino uno is an open source microcontroller board that is based on the microchip atmega328p for arduino uno r3 or microchip atmega4809 for arduino uno wifi r2 micro controller by atmel and was the first usb powered board developed by arduino. The arduino uno is arguably the most popular arduino board currently available. In here i will get into details with the basic arduino schematic diagram using one of their more popular development board the arduino uno.
