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.
English: This is a diagram for connecting an LED to the GPIO header of an Raspberry Pi. The original schematic was made by Software11, corrections were made by Toble Miner, and a revised vector version was made by Alex Rosenberg35.
Revision 1.2 features a 900 MHz 64-bit quad-core ARM Cortex-A53 processor (the same as that in the Raspberry Pi 3 Model B, but underclocked to 900 MHz). [22] The Raspberry Pi 3 Model B was released in February 2016 with a 1.2 GHz 64-bit quad core ARM Cortex-A53 processor, on-board 802.11n Wi-Fi, Bluetooth and USB boot capabilities. [23]
The microcontroller is low cost, with the Raspberry Pi Pico 2 being introduced at US$5 and the RP2350 itself costing as little as US$0.80 in bulk. The microcontroller is software-compatible with the RP2040 and can be programmed in assembly , C , C++ , Free Pascal , Rust , MicroPython , CircuitPython , and other languages.
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.

Raspberry Pi, a popular modern-class microcomputer A microcomputer is a small, relatively inexpensive computer having a central processing unit (CPU) made out of a microprocessor . [ 2 ] The computer also includes memory and input/output (I/O) circuitry together mounted on a printed circuit board (PCB). [ 3 ]
One of the company's objectives was to make the product affordable to schools and school children and, in 2015, it launched the Raspberry Pi Zero at a selling price of US$5 or £4. [ 4 ] In 2021, Raspberry Pi (Trading) Ltd changed its name to Raspberry Pi Ltd. [ 2 ] [ 5 ] Its newly-formed holding company, Raspberry Pi Holdings, was the subject ...
