Question

What is the operating frequency of the Arduino UNO Board?

(a) 20 MHz

(b) 16 Mhz

(c) 6 MHz

(d) 10 MHz

The question was posed to me in my homework.

I would like to ask this question from Board Hardware Specifications in division Board Specifications and Types of Arduino

Answer 1

Correct answer is (b) 16 Mhz

The best explanation: The Arduino UNO makes use of the ATmega328 Processor which has an operating frequency of 16 MHz and a maximum operating frequency of 20 MHz which is not advisable since the higher the switching speed, the hotter the chip will get and may even lead to physical damage of the board.
