The Arduino Uno can work with a range of voltages which are regulated down to the 5V needed for the board. It can draw more current if usedįlexibility is the winning feature here. An Arduino Uno can pull a maximum of 500mA via USB. So a Raspberry Pi 4 could theoretically run at up to 15W.
With the Raspberry Pi 4 there was a new USB C power connector and a higher rated official power supply unit providing up to 3A for the Pi and any devices connected to it. When it comes to power consumption, the Raspberry Pi 4 is quite a hungry board. Power Requirements: Raspberry Pi vs Arduino But the Raspberry Pi needs the greater power as it also runs an operating system. The lowest spec Raspberry Pi which we can buy is the Raspberry Pi Zero W, which has a single 1GHz CPU and still provides more raw power than the dual core 480MHz STM32H747. Arduino’s Portenta H7 is a powerful board, but it cannot match the Pi in power. It is reliable and there is no scaling which could cause timing issues for projects that require absolute accuracy.įor sheer CPU power the Raspberry Pi was always the clear winner. But there is something to be said for a CPU with a fixed speed. If we ran a test based on pure “horsepower” then the Raspberry Pi would clearly win. These chips are considerably slower than those found in the Raspberry Pi, but the Arduino does not have as many overheads such as running a Linux operating system. For example, the Arduino Uno runs at 16MHz. The Arduino models are typically powered by Atmel microcontrollers and are often less than 100MHz. From the original single core 700MHz model in 2012, to the quad-core 1.5GHz model of now. The Raspberry Pi has many different models all powered by an ARM CPU.
