-==== Raspberry Pi General Information ====
+The Raspberry Pi is a series of small single-board computers developed in the UK by the Raspberry Pi Foundation to promote modern computer science in schools and create electronic communities. Adding the 40-pin GPIO connector to the computer board allows developers to improve their programming skills and opens new horizons in controlling processes and devices unavailable for desktop computers. According to the Raspberry Pi Foundation, the board's sales in July 2017 reached nearly 15 million units.
-<box #5374d5></box>
+The first generation of this new board type was developed and then released in February 2012 – **Raspberry Pi Model B**. Each Raspberry Pi board contains hardware modules which together make it a wholly usable PC like a computer whose size fits the typical credit card (85/56 mm) size and small power consumption < 3.5 W. This makes this kind of single board computer one of the most popular in the developers' community. Today, thousands of hardware implementation projects exist for users who want to learn modern hardware and software controlling units and include them in their projects.

-There are a dozen clones, even more powerful, sharing a common concept, size, and connectors (mostly GPIO, USB, Ethernet and CSI/DSI) with genuine RPIs, such as OrangePi, BananaPi and others. They differ in CPU (MCU), GPU, and RAM, and some are even more powerful than genuine Raspberries. Still, they are ARM-based and powered with Android or Linux.
 Because the power consumption in the latest devices, such as Raspberry Pi 4 and 5, can exceed 20W, they are considered mains powered and, thus, in the IoT ecosystem, play the role of gateways, routers and, in general, fog-class devices rather than edge-class. Still, this classification is fuzzy as there are dozens of examples of how to use Raspberry Pi, e.g. sensors-network component.
-Besides advanced fog-class devices, Raspberry recently started to hit the edge-class IoT development market (low-powered, end node devices) with their RP2040 MCU.

-==== Hardware ====
-Hardware boards (depending on the manufactured model) contain interfaces:  Ethernet, Bluetooth, WiFi, USB, AUDIO, HDMI and GPIO ports ((https://www.raspberrypi.org/documentation/hardware/raspberrypi/README.md)). The Raspberry Pi boards have evolved through several versions varying in memory capacity, System on Chips (SoC) and processor units. The first generation models of Raspberry Pi used the Broadcom BCM2835 (ARMv6 architecture) based on a 700 MHz ARM11176JZF-S processor and VideoCore IV graphics processing Unit (GPU). Models Pi 1 and B+ developed later use the five-point USB/Ethernet hub chip while the Pi 1 Model B only contains two. On the Pi Zero, the USB port is connected directly to the SoC and uses the (OTG) micro USB port.
-The Raspberry Pi pico is the board that uses the chip RP2040 designed by Raspberry Pi. It is intended for use as a low-cost, low-power device with quite big computational possibilities. Raspberry Pi decided also to make the RP2040 chip available for buying to make it possible for designers to create their own projects.
-<todo @pczekalski> RP2040 description </todo>
-==== Processor ====
-The first Raspberry Pi 2 models use the 900 MHz Broadcom BCM2836 SoC 32-bit quad-core ARM Cortex-A7 processor, with a shared 256 KB L2 cache. After these earlier models, the Raspberry Pi 2 V1.2 has been upgraded to a Broadcom BCM2837 SoC equipped with a 1.2 GHz 64-bit quad-core ARM Cortex-A53 processor. Next Raspberry Pi 3 series uses the same SoC. They use the Broadcom BCM2837 SoC with a 1.2 GHz 64-bit quad-core ARM Cortex-A53 processor, equipped with 512 KB shared L2 cache. The Raspberry Pi 3B+ uses the same processor (BCM2837B0) running at 1.4 GHz. The Raspberry Pi 4 is based on Broadcom BCM2711, a quad-core Cortex-A72 64-bit SoC working at 1.5 GHz. Next Raspberry Pi generations are going to be more and more powerful, but their power consumption is still rising to force developers to use CPU and GPU heatsinks.
-==== RAM ====
-The initial Raspberry Pi boards were designed with 128 MB RAM which was by default allocated between the GPU and CPU. In the newer edition (including Model B and Model A) the RAM was extended to 256 MB and split into the regions. The default split was 192 MB (RAM for CPU), which is sufficient for standalone 1080p video decoding, or for 3D modelling. Models B with 512 MB RAM initially, memory was split into files released (arm256_start.elf, arm384_start.elf, arm496_start.elf) for 256 MB, 384 MB and 496 MB CPU RAM (and 256 MB, 128 MB and 16 MB video RAM). The Raspberry Pi 2 and 3 are shipped with 1 GB of RAM. The Raspberry Pi 4 can be equipped with 1, 2, 4 or even 8 GB of RAM memory. The Raspberry Pi Zero and Zero W contains 512 MB of RAM.
-==== Networking ====
-The Model A, A+ and Pi Zero have no dedicated Ethernet interface and can be connected to a network using an external USB Ethernet or WiFi adapter. In Models B and B+, the Ethernet port is built-in to the USB Ethernet adapter using the SMSC LAN9514 chip. The Raspberry Pi 3 and Pi Zero W (wireless) models are equipped with 2.4 GHz WiFi 802.11n (150 Mbit/s) and Bluetooth 4.1 (24 Mbit/s) based on Broadcom BCM43438 FullMAC chip. The Raspberry Pi 3 also has a 10/100 Ethernet port. The latest Raspberry Pi 4 contains a dual band 2.4 / 5 GHz WiFi network adapter (IEEE 802.11ac), Bluetooth 5.0, and Gigabit Ethernet.
-==== Peripherals ====
-The Raspberry Pi may be controlled with any generic USB computer keyboard and mouse. It can also use USB storage, USB to MIDI converters, and virtually any other device/component which is USB compatible.
-Other peripherals can be attached through the various pins and connectors on the surface of the Raspberry Pi.
-==== Video subsystem ====
-The video controller supports standard modern TV resolutions, such as HD and Full HD, and higher. It can emit 640 × 350 EGA; 640 × 480 VGA; 800 × 600 SVGA; 1024 × 768 XGA; 1280 × 720 720p HDTV; 1280 × 768 WXGA variant; 1280 × 800 WXGA variant; 1280 × 1024 SXGA; 1366 × 768 WXGA variant; 1400 × 1050 SXGA+; 1600 × 1200 UXGA; 1680 × 1050 WXGA+; 1920 × 1080 1080p HDTV; 1920 × 1200 WUXGA. Higher resolutions, such as, up to 2048 × 1152, may work or even 3840 × 2160 at 15 Hz. Although the Raspberry Pi 3 does not include H.265 hardware decoders, the CPU is more powerful than its predecessors, potentially fast enough for software decoding of H.265-encoded videos. The Raspberry Pi 3 GPU runs at a higher clock frequency -- 300 MHz or 400 MHz, compared to 250 MHz in previous versions. The Raspberry Pi is capable of generating 576i and 480i composite video signals, as used on old-style (CRT) TV screens and less-expensive monitors through standard connectors – either RCA or 3.5 mm phono connector depending on the models. The television signal standards supported are PAL-BGHID, PAL-M, PAL-N, NTSC and NTSC-J. The Raspberry Pi 4 has two micro HDMI connectors that support 4K displays with a refreshing rate of 60Hz.
-==== Real-Time Clock ====
-None of the current Raspberry Pi models is equipped with a built-in real-time clock. Developers which needs the real clock time in their project can retrieve the time from a network time server (NTP) or use the external RTC module connected to the board via SPI or I²C interface. To save the file system consistency of time, the Raspberry Pi automatically saves the time on shutdown, and reload it time at boot. One of the best RTC solutions for keeping the proper boards time is to use the I²C DS1307 chip containing hardware clock with battery power supply.

-====USB and LAN Ports====
-Raspberry PI models Zero, 1, A+, 2, 3, 4 and 5 contain USB ports (from 1 up to 4), and all but Zero also have a LAN port for TCP/IP network connections. These ports can be used for mouse/keyboard connection or if the software has the appropriate driver installed to handle other USB devices.
-Since generation 4, devices are equipped with 2 USB 3.0 ports as in figure {{ref>rpiports}}.
-Starting with Raspberry 3B+, the Ethernet port is a gigabit one that can reach up to 1Gbps, theoretically. Prior 3B (including) it is fast Ethernet, 100Mbps.
-<note tip>In RPI 3B+, gigabit Ethernet is connected internally to the USB 2.0 controller with a maximum throughput of about 480Mbps (practical 200Mbsp); thus, the maximum transfer is limited.</note>
