== Hardware ==
Since its introduction, Raspberry Pi hardware has been designed to provide low-cost computing platforms. The founders intended it to be an affordable and accessible system, even for users in developing countries, by making it compatible with widely available second-hand peripherals—such as televisions for displays, USB input devices, and cellphone chargers for power. Over time, the hardware has expanded to support both advanced configurations and ultra-low-cost variants.<ref>{{Cite web |last=Khaliq |first=Azzief |date=27 April 2024 |title=The Evolution Of Raspberry Pi: From Prototype To Single-Board Computing Workhorse |url=https://www.slashgear.com/1566508/raspberry-pi-history-evolution-small-single-board-computer/ |access-date=26 November 2024 |website=SlashGear}}</ref>
Raspberry Pi hardware is also known for its long-term availability, with the company committing to keep products in production for up to ten years. This approach is particularly valued by business customers, as the devices are often integrated into embedded systems and long-lived equipment. This industrial and embedded-use market accounted for 72 per cent of sales in 2023, while the company’s original target markets—education and hobbyist users—represented the remaining 28 per cent.
All models include a processor, memory, and various input/output interfaces on a single circuit board. Most include an HDMI output, USB ports, and a GPIO ([[general-purpose input/output]]) header. Networking capabilities vary by model, with later versions featuring integrated Wi-Fi and Bluetooth.<ref>{{cite web |date=15 September 2016 |title=Raspberry Pi 3 Model B WiFi & Bluetooth Setup |url=https://www.deviceplus.com/raspberry-pi/raspberry-pi-3-model-b-wifi-bluetooth-setup/ |access-date=17 November 2020 |website=Device Plus}}</ref> Storage is typically provided via a microSD card, with newer models supporting USB or [[PCI Express|PCIe]]-based boot options.<ref name=":0">{{Cite web |last=Geerling |first=Jeff |title=I'm booting my Raspberry Pi 4 from a USB SSD |url=https://www.jeffgeerling.com/blog/2020/im-booting-my-raspberry-pi-4-usb-ssd |access-date=14 July 2021 |website=JeffGeerling.com}}</ref><ref name=":1">{{Cite web |last=Geerling |first=Jeff |date=14 May 2024 |title=microSD cards' SBC days are numbered |url=https://www.jeffgeerling.com/blog/2024/microsd-cards-sbc-days-are-numbered |access-date=8 June 2025 |website=JeffGeerling.com}}</ref>
