1. Which Arduino uses ATmega328P?
- Arduino Uno Wifi module is suitable for both beginners and advanced Learners, this board can be used for almost any project thanks to its versatility. This is a modified version of the classic Arduino UNO R3 board. Fully integrated ATmega328 microcontroller and his IO ESP8266 with 32MB flash memory and USB-TTL converter CH340G. All modules can work together or independently. The atmega328p Arduino compatible to esp8266 board has wifi feature which makes it easier to use for Home automation and IoT projects. Atmega328p smd pinout are similar to that of Arduino Uno.
2. Does the Arduino Uno have Wi-Fi?
- No, The Arduino Uno does not come with inbuilt WiFi. The Arduino Uno atmega328p board with WIFI is similar development board with inbuild wifi. This Arduino Uno wifi board can be used as a replacement for the Arduino Uno. The Arduino uno wifi esp8266 connection is possible with the help of the Uno+Wifi Board.
3. Why ATmega328 is used in Arduino Uno?
- The Arduino Uno's ATmega328 comes pre-programmed with a bootloader that allows new code to be uploaded without the use of an external hardware programmer. Communicate using the original STK500 protocol. The ATmega328P is a high performance, low power 8-bit AVR microcontroller with an advanced RISC architecture capable of executing 131 instructions in almost a single clock cycle.
4. Is Arduino and Atmega328 same?
- The Atmega328 is like a brain of Arduino that commands the Arduino to perform any particular task. So, Arduino and Atmega328 are not the same thing but All the Arduino has atmega328 inbuilt in it.
