Arduino Uno Board Schematic Diagram. Atmega 328p based arduino uno pinout and specifications are given in detail in this post. Arduino disclaims all other warranties express or implied arduino may make changes to specifications and product descriptions at any time without notice.
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. Here the arduino uno schematic diagram click to enlarge.
Redistributed version of the original arduino schematic.
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. The arduino uno is really a microcontroller board based on the atmega328. 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. 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.
