The Raspberry Pi has an ARM11 700 MHz processor. It includes 1, 2 or 4 USB ports, an RJ45 port and 256 MB of RAM for the original model up to 4 GB on the latest versions. Its BMC VideoCore 4 graphics circuitry can decode full HD Blu-Ray streams (1080p 30 frames per second), emulate old consoles and play relatively recent video games.
The first computer at $ 5! The ultra-thin and ultra-thin Raspberry Pi Zero is the smallest Raspberry Pi form factor on the market. It is 40% faster than the original Raspberry Pi but is only 65 mm long by 30 mm wide and 5 mm deep.
The Raspberry Pi Zero supports mini-connectors to save space and the 40-pin GPIO is unpopulated, which offers the flexibility to use only the connections necessary for your project.
The Raspberry Pi Zero W! It is the smallest of the Raspberry Pi family, it also has Wi-Fi and integrated Bluetooth connectivity!
With a processor as powerful as the A + and the B +, the Raspberry Pi Zero W will offer you many possibilities, thanks to its compact design.
You will need a 2x20 GPIO header to connect most of expansion cards!
The Raspberry Pi 1 Model A+ Is just 56mm long, 12mm thick and uses up to 45% less power than a Raspberry Pi 1 Model B+
Discover the Raspberry Pi 3 Model B 1GB with integrated Wi-Fi and Bluetooth connectivity!
Based on the Quad Core Broadcom 2837 ARMv8 64bit processor going from 900MHz (on Pi2) to 1.2Ghz, the new generation RPi is a little larger than Pi2, faster and more powerful than its predecessors.
The Raspberry Pi 3 Model B + has a 1.4-bit quad-core processor clocked at 1.4 GHz, a 2.4 GHz and 5 GHz dual-band wireless network, a Bluetooth 4.2 / BLE connection, a faster Ethernet connection and the possibility of a PoE power via PoE HAT (not included).
The latest Raspberry Pi 3 model B + has a faster 64 GHz 1.4-bit quad core processor, 1 GB of RAM, a faster 802.11 b / g / n / ac dual-band wireless LAN, Bluetooth 4.2 and an Ethernet 300 Mbit/s much faster.
With the ARMv8 processor, it can run the full range of ARM GNU / Linux distributions, including Snappy Ubuntu Core, as well as the IoT edition of Microsoft Windows 10.
With up to 8GB of memory, this Raspberry PI4 is the most powerful Pi4 and retains exceptional capabilities over the Pi3 and Pi3 Model B+.
It offers an unprecedented increase in processor speed, multimedia performance, memory and connectivity over the previous generation Raspberry Pi 3 Model B+, while maintaining compatibility with previous versions and similar power consumption. In addition, thanks to a 1.3 revision, the Raspberry Pi 4 can support more memory.
For the end user, the Raspberry Pi 4 Model B offers desktop performance comparable to that of entry-level x86 PC systems.
The Raspberry Pi 400 is based on a Raspberry Pi 4, with a little boost.
On the technical level the Pi 400 is built on the basis of the Raspberry 4, same ports, same graphics capabilities, same memory, same power supply, etc.
The GPIO ports are of course kept and easily accessible on the keyboard side dedicated to the connectors.
The only technical difference is the processor speed, which has been increased from 1.5 Ghz for the Raspberry 4 to 1.8 Ghz for the Raspberry 400.
The shape of the Raspberry Pi 4 has also been completely redesigned to fit this new format, as shown in this image from the foundation.
Another difference is that thanks to its less compact shape and the use of integrated heat sinks (the gray part of the image above), this Raspberry Pi 400 should heat up much less than the Raspberry Pi 4.
