![]() ![]() It doesn’t mean that the Arduino is worse than Raspberry Pi for everything. On Arduino, you have much lower CPU resources (about 100 times less than Raspberry Pi), and the memory (SRAM) is really, really small (a few KB). You don’t really have control over that and if you run multiple programs at the same time, you can’t be sure that you’ll achieve real-time constraints with one specific program. ![]() However, on Raspberry Pi, with Raspbian or Ubuntu for example, the operating system is managing the resources for you. On Raspberry Pi, you have much bigger CPU, multiple cores, and much more RAM, so basically you can run much bigger programs. The performance is different in many ways. There are some things that you can only do with an Arduino board. Also, you saw that both boards have similar hardware functionalities, but there are still big differences there. Let’s now try to see the major differences between Arduino vs Raspberry Pi boards, by focusing on the real use you’ll make of each.įor now, as you can see, the main difference is about the control component: microprocessor vs microcontroller. To program on Arduino you’ll need to install the Arduino IDE and upload the program to your board, from your own computer. With those pins you can do many things: read data from sensor (digital, analog, SPI, I2C, UART, …), create a PWM, control a motor with a special driver, communicate with other boards and devices, etc. On the board you also have many hardware pins, mostly digital and analog inputs/outputs. All you have is a program running in a loop. On an Arduino microcontroller you don’t get to install an OS. A microcontroller is very different from a microprocessor. Depending on the Arduino type you can have a different microcontroller – same family (ATMega) for Arduino Uno, Mega and Nano. ArduinoĪn Arduino board contains a microcontroller. Those GPIOs allow you to read data from sensors, give commands to an actuator, or even communicate with other Raspberry Pi/Arduino boards. The Raspberry Pi also has some hardware specifics features that you don’t find in a personal computer. You can play Minecraft quite easily with your Pi! ![]() One of the most well-known example of a Desktop application running on Raspberry Pi is Minecraft. You can plug a screen on the HDMI port, a keyboard and a mouse on the USB ports. ![]() Basically you can use the Raspberry Pi just like you would use your own computer (with some performance limits though). This microprocessor has an ARM architecture and can run a complete OS (Raspbian, Ubuntu). Raspberry PiĪ Raspberry Pi board contains a microprocessor. Even if they are similar and can be both embedded – thanks to their size, they are two completely different kinds of boards. Main differences between Arduino vs Raspberry Pi boardsįirst of all you need to understand the fundamental differences between the two boards.
