The Raspberry Pi 4 is the 4th generation of the mainline series of Raspberry Pi single-board computers.Developed by Raspberry Pi (Trading) Ltd [1] and released on 24 June 2019, the Pi 4 came with many improvements over its predecessor; the SoC was upgraded to the Broadcom BCM2711, two of the Raspberry Pi's four USB ports were upgraded to USB 3.0, and options were added for RAM capacities ...
Raspberry Pi 1 Models A+ and B+, Pi 2 Model B, Pi 3 Models A+, B and B+, Pi 4, and Pi Zero, Zero W, Zero WH and Zero W 2 have the same 40-pin pinout (designated J8 across all models). [119] Raspberry Pi 1 Models A and B have only the first 26 pins.

Announced on 21 January 2021, the RP2040 is the first microcontroller designed by Raspberry Pi Ltd. [1] [2] The microcontroller is low cost, with the Raspberry Pi Pico being introduced at US$4 and the RP2040 itself costing US$1.
RAM access tested using the mbw benchmark is 25% faster than the Raspberry Pi 3. SD card (microSD) access is about twice as fast at 37 MiB/s for buffered reads (compared to typically around 18 MiB/s for the Pi 3 [ 30 ] ) due to the Tinker Board's SDIO 3.0 interface, while cached reads can reach speeds up to 770 MiB/s.
Display Serial Interface connector on Raspberry Pi single-board computer. The Display Serial Interface (DSI) is a specification by the Mobile Industry Processor Interface (MIPI) Alliance aimed at reducing the cost of display controllers in a mobile device. It is commonly targeted at LCD and similar display technologies.
Some boards, which are classified usually as multi-function I/O boards, are a combination of both; such boards provide GPIOs along with other types of general-purpose I/O. GPIOs are also found on embedded controller boards and Single board computers such as Arduino, BeagleBone, and Raspberry Pi.
The Raspberry Pi (Model 2B shown) is a low-cost single-board computer often used to teach computer science. [1]A single-board computer (SBC) is a complete computer built on a single circuit board, with microprocessor(s), memory, input/output (I/O) and other features required of a functional computer.
