Difference between Arduino and Raspberry Pi

There are a wide variety of controller boards that we can use for our hardware projects. The two most popular among them are: Arduino and Raspberry Pi.

Arduino is based on the ATmega family and has a relatively simple design and software structure. Raspberry Pi, basically is a single-board computer. Both of them have a CPU which executes the instructions, timers, memory and I/O pins. The key distinction between the two is that Arduino tends to have a strong I/O capability which drives external hardware directly. Whereas Raspberry Pi has a weak I/O which requires transistors to drive the hardware.

Let’s see the difference between Arduino and Raspberry Pi :-



S No. Arduino Raspberry Pi
1. Control unit of Arduino is from Atmega family. While control unit of Raspberry Pi is from ARM family.
2. Arduino is based on a microcontroller. While Raspberry Pi is based on a microprocessor.
3. It is designed to control the electrical components connected to the circuit board in a system. While Raspberry Pi computes data and produces valuable outputs, and controls components in a system based on the outcome of its computation.
4. Arduino boards have a simple hardware and software structure. While Raspberry Pi boards have a complex architecture of hardware and software.
5. CPU architecture: 8 bit. CPU architecture: 64 bit.
6. It uses very less RAM, 2 kB. While Raspberry Pi requires more RAM, 1 GB.
7. It clocks a processing speed of 16 MHz. While Raspberry Pi clocks a processing speed of 1.4 GHz.
8. It is cheaper in cost. While Raspberry Pi is expensive.
9. It has a higher I/O current drive strength. While Raspberry Pi has a lower I/O current drive strength.
10. It consumes about 200 MW of power. While it consumes about 700 MW of power.
