Difference Between Arduino and Raspberry Pi

Arduino  Raspberry Pi
Most important parameter which distinguishes both the boards is the processing unit.
Arduino uses an 8-bit Atmega328P “Microcontroller.” So it is a MCU-based development board.
Raspberry Pi is a credit card size computer that uses 4th gen Broadcom Advanced/Acorn Reduced Instruction Set (ARMv8) BCM2711 Cortex-A72,
64-bit quad-core with 4 threads SoC “Microprocessor” as a processing unit.
No operating system is required. The operating system is required for booting.
Can run just one task at a time. Can do multiple tasks simultaneously
Since Arduino is a microcontroller peripheral like processor, RAM, ROM are inside MCU itself. Here RAM is fixed( 2KB SRAM) and flash(32KB) Since Raspberry Pi uses a microprocessor we externally connect RAM,memory for storage(128GB or more),etc.
This is the reason why Raspberry Pi 4B comes in different RAM variants 1GB,2GB,4GB, and 8GB.
Clock frequency:16Mhz Clock frequency:1.5Ghz
20 GPIO pins( 5V voltage level): 14 digital and 6 analog 40 GPIO pins (3.3V voltage level make sure you always check external devices while connecting to the pins):
40 digital and no analog support(external ADC circuit required)
No USB support. USB support( for connecting mouse, keyboard, etc)
Display support through GPIO. Display support through 2 * micro HDMI ports ( dual-display support) + through GPIO.
Wireless connectivity: Wifi and Bluetooth need to be externally connected. On-board wireless connectivity: wifi (2.4Ghz and 5.0 GHz IEEE 802.11ac)
and Bluetooth 5.0
No ethernet port Gigabit Ethernet port
C, C++ is used as a programming language. Python, C, C++, Java, etc can be used as a programming languages.
PC is required to program. Direct programmability no need of PC
Consumes 10 timeless power than Rpi Consumes a lot of power than Arduino
Open-source( Hardware and software info is readily available on the Internet) Proprietary closed system( Hardware and firmware are not readily available on the internet.)
Cost: $25( Official store price) Cost $45 (2 GB RAM)

Why was the Arduino created?

To make inexpensive and faster prototypes that interact with the environment using sensors and actuators.

Example: Home automation using Arduino. You don’t need to analyze and completely understand assembly or microcontroller programming or microcontroller architecture otherwise you would have to configure each and every register that you want to use. Just getting an idea about how things work from surface level is enough. For this Arduino provides different libraries. Example: Arduino provides UART or Serial library so you don't need to configure UART registers. Just import the library and write the code, Arduino takes care of the backend stuff i.e. configuring registers.
Other than this it also offers lots of other advantages like
Open-source hardware and software: Open source makes it easy for experienced circuit designers and programmers to modify and improve current hardware and software.

  • Arduino is limited in its ability to execute intricate tasks.

What is Raspberry Pi?

The Raspberry Pi is a low-cost, credit-card-sized computer (monitor, keyboard, and mouse when connected to the development board).

Why was Raspberry Pi created?

In 2006 in the UK Eben Upton(creator of Raspberry Pi) realized that there was a problem in UK education - computers were expensive. Since they were expensive young students didn't learn computer science and rejected this path. Moreover, companies in the UK also lacked computer professionals. In order to solve these problems, Raspberry Pi was invented.

The main goal was to release computers for less price around $30 and make students interested in computer science.

Features of Raspberry Pi:

  • Superior software implementation
  • 64-bit Quad-core processor
  • Large RAM (latest Raspberry Pi 4 Model B Board has up to 8G of RAM)
  • Processor speed- 700MHz- 1.5GHz
  • Raspberry Pi has 40 input/output pins.
  • It can be connected to the Internet.
  • It can run all kinds of applications (including MS Office and Email).
  • It contains everything- CPU (Central Processing Unit), GPU (Graphics Processing Unit), Ethernet port, GPIO (General-purpose Input/Output) pins, and power source connector.

Advantages and Disadvantages of Raspberry pi


  • Capable of executing intricate tasks like weather monitoring and robot control due to its operating system support.
  • Functioning as a portable computer, it encompasses essential components, including a CPU, ethernet port, and WiFi capability.
  • Abundance of GPIO pins (40 in the renowned Raspberry Pi model) accommodates numerous sensors.
  • Boasting enhanced processing power, the 4 B variant features a 1.6 GHz processor.
  • Versatility extends to running diverse applications, encompassing MS Office and email.


  • Raspberry Pi's hardware and software are proprietary, preventing customization of your own Raspberry Pi single-board computer (SBC).
  • For internal storage, Raspberry Pi lacks native capacity, necessitating a micro SD card.
  • Under strenuous operations, instances of overheating may arise.

The Main goal of Arduino

To create an easy way for software developers or people of all ages to enter the world of microcontroller programming.

The main goal of Raspberry Pi

To enable people of all ages to explore computer science, and computing and learn how to program in languages like Scratch and Python.

Which one to choose?

If you are completely new to electronics and want to start learning hardware prototyping then We personally would recommend you to go with Arduino Uno since most people start from Arduino and also since it's easy to learn. After 2-3 months of practice with Arduino, you can then buy a Raspberry Pi too.
If you are planning to buy just one board then it depends on the application that you are doing. So if you are a person who wants to buy a board just for a “particular application” then based on the application requirement choose the board. Example: Raspberry pi can be used as a web server which we can't do just with Arduino Uno. If your application involves interfacing with sensors and motors you can go with
Arduino Uno since using Raspberry pi would increase the cost by 5 times.
