I bought a 16Hertz Uno R3 Board. When I installed the driver and the Arduino IDE, in the IDE`s menu I saw:
Tools -> Board -> Arduino Uno
was selected by default which is great, but...
Tools -> Port -> COM3(Arduino Mega or Mega 2560)
was selected by default which I think might be some kind of misunderstanding...
When I chose:
Tools -> Board -> Arduino Mega or Mega 2560
On that tools menu appeared new menu "Processor" with two options:
Tools -> Processor -> ATmega2560 (Mega 2560)
which was selected by default and there was another option
Tools -> Processor -> ATmega1280
When I restore Tools -> Board settings back to "Arduino Uno" the "Processor" menu with the two options disappeared and Tools -> Port setting did not changed!
If you take my board and look at the Microcontroller there is written:
Also on that board is written:
I need to know:
- What does 16Hz mean? Does it mean the clock or frequency of this Microcontroller? I think it does not, if I try to find out details of my Microcontroller on the rs-online site, there is written:
ATMEGA328P-PU, 8 bit AVR Microcontroller 20MHz 1 kB, 32 kB Flash, 2 kB RAM, I2C 28-Pin PDIP
- Why was there "COM3(Arduino Mega or Mega 2560)" written on the Port's menu?
- Is my 16Hz Uno R3 and the Arduino Uno R3 board the same? Which one is better? When one of those is better?
- Does the standard Arduino Uno R3 board have the same ATMEGA328P-PU Microcontroller?
