Native Internet and Bluetooth connectivity (some models).Strengths and WeaknessesĪ quick, and by no means exhaustive, comparison of the two platforms looks like this: It’s a small (67.6mm × 31mm) board that fits into a standard DDR2 SODIMM connector, just like a memory chip. The Raspberry Pi Compute Module allows you to integrate an entire Raspberry Pi into your commercial product. This makes it easy to incorporate an Arduino within your commercial product. The Raspberry Pi is a commercial product that is licensed for manufacture at a limited number of factories worldwide and distributed through licensed vendors.Īrduino’s are based upon popular AVR chips and designs based upon Arduino’s can be easily reworked using these chips. The Arduino is an open-source design, which is why there are so many Arduino “clones” and Arduino variations. It is capable of precision timing and it is built around inexpensive components. Not a computer, a small controller, whose purpose in life is to (what else?) control things! It accepts inputs from analog and digital sources and provides digital outputs. The Arduino, on the other hand, is a microcontroller. It also communicates using Bluetooth, Wifi, and RJ-45, although the networking capabilities vary between models. It interfaces to a video monitor (or two), to a keyboard, mouse and other USB devices. It runs an operating system and has the equivalent of a hard drive, the latter in the form of a microSD card. The Raspberry Pi is a microcomputer, literally a small computer.
Each has its own strengths and weaknesses, which need to be taken into consideration when choosing a device to base your design upon.
There is a tendency to want to compare the Raspberry Pi with the Arduino, which is not really a proper comparison as they aren’t even the same category of device.
So it’s a good thing to learn about, even if you plan on using another board.

The Raspberry Pi 40-pin GPIO has been unofficially adopted by many SBC (Small Board Computer) manufacturers, allowing designs and code for the Raspberry Pi to be ported onto other platforms. Pretty well any digital I/O sensor or device that you can interface to an Arduino can be attached to a Raspberry Pi using the GPIO, allowing your designs to benefit from the increased speed, storage, and power the Pi provides. The GPIO is also ideal for experimenters and makers who want to interface their Raspberry Pi with the outside world. The bus provides access to power (5v and 3.3v), communications and general-purpose digital I/O signals. The GPIO allows you to expand your Raspberry Pi using expansion boards called HATs, an acronym for Hardware Attached on Top. Original models used a 26-pin bus but all modern Raspberry Pi boards have a 40-pin GPIO. The Raspberry Pi GPIO (General Purpose Input/Output) bus is a connector found on every model of Raspberry Pi.
