making" magazine. Products Raspberry Pi In 2011, the Raspberry Pi Foundation developed a single-board computer named the Raspberry Pi. The Foundation's goal was to offer two versions, priced at US$25 and $35 (plus local taxes). The Foundation started accepting orders for the higher priced model on 29 February 2012. Since then, several models with increased performance have been released. The Raspberry Pi is intended to stimulate the teaching of computer science in schools. Raspberry Pi Zero In 2015 the foundation announced the Raspberry Pi Zero. This version of the microcomputer had a significantly reduced form factor and a lower price, launching at £4/$5. The new model features a 1 GHz, single-core CPU; 512 MiB RAM, USB and mini HDMI ports, micro USB power, and a HAT-compatible 40-pin header as well as composite video and reset headers . As a fully functioning Linux system the Raspberry Pi Zero's 1 GHz processor is comparable to the middle of the road for the Intel Pentium 3 architecture (450 MHz to 1.4 GHz), a standard in 2000. The reduced price and smaller form factor encourages use in smaller and embedded projects. Raspberry Pi Pico Raspberry Pi Pico was released in January 2021 with a retail price of $4. It was Raspberry Pi's first board based upon a single microcontroller chip; the RP2040, which was designed by Raspberry Pi in the UK. The Pico has 264 KB of RAM and 2 MB of flash memory. It is programmable in MicroPython, CircuitPython, C and Basic. It has partnered with Vilros, Adafruit, Pimoroni, Arduino and SparkFun to build Accessories for Raspberry Pi Pico and variety of other boards using RP2040 Silicon Platform. Rather than perform the role of general purpose computer (like the others in the range) it is designed for physical computing, similar in concept to an Arduino.
