Overview

About Raspberry Pi 4 Model B (4GB).

The Raspberry Pi 4 Model B (4GB) remains one of the most popular and best-value single-board computers, offering a genuine desktop-class experience in a credit-card-sized board. It runs a 1.5 GHz quad-core Arm Cortex-A72 processor with 4GB of LPDDR4 RAM, dual micro-HDMI outputs, USB 3.0 and true Gigabit Ethernet.

It is extremely common in India for desktop use, home labs, retro gaming, network appliances (Pi-hole, home servers, VPNs), robotics and IoT gateways. The enormous community, mature software support and years of tutorials mean almost any project you can imagine has a proven guide built around the Pi 4. The 4GB variant hits the sweet spot of enough memory for multitasking without paying for the top model.

With a full 40-pin GPIO header it drives the entire ecosystem of HATs and add-on boards, and it runs the well-supported Raspberry Pi OS as well as many other Linux distributions. It draws less power and runs cooler than the Pi 5, making it a dependable everyday choice.

Buying guide

How to choose.

Choose the Pi 4 Model B (4GB) when you want a proven, well-supported single-board computer for a desktop, home server or robotics brain without the higher power draw and cost of the Pi 5. The 4GB variant is the balanced pick for most everyday multitasking.

If you only need light IoT or a compact embedded controller, the smaller Pi Zero 2 W is cheaper and tinier. If you need maximum speed, PCIe/NVMe or heavier AI work, step up to the Pi 5. Buy the Pi 4 when value, low power and mature software matter most.

Pair it with a good 5V/3A USB-C power supply, a case with a heatsink or fan (the Pi 4 can get warm under load), an A2-rated microSD card, and micro-HDMI cables since it does not use full-size HDMI. A quality power supply avoids under-voltage warnings.

FAQ

Common questions.

How is the Raspberry Pi 4 powered?

It uses a USB-C power input and needs a good 5V/3A (15W) supply, ideally the official Raspberry Pi adapter. Underpowered phone chargers often trigger low-voltage warnings and instability, so use a proper supply rated for the Pi 4.

What is the difference between the 4GB and 8GB Pi 4?

They are otherwise identical; only the RAM differs. 4GB is plenty for desktop use, servers, most projects and multitasking. Choose 8GB only if you run many heavy applications, large in-memory workloads or multiple containers at once.

Does the Pi 4 need cooling?

For light use it is usually fine bare, but under sustained load the CPU can throttle. A simple heatsink handles most tasks, and a fan case keeps it cool for continuous heavy workloads. Cooling is inexpensive and recommended for servers or long-running jobs.

Can I use the Pi 4 as an everyday desktop?

Yes, for web browsing, office documents, coding and media it works well, especially with 4GB RAM and an SSD over USB 3.0 instead of a microSD card. Very heavy multitasking or demanding apps are better on the Pi 5, but the Pi 4 handles typical desktop use comfortably.

What do I need besides the board to get started?

You need a 5V/3A USB-C power supply, a microSD card (flashed with Raspberry Pi OS using Raspberry Pi Imager), micro-HDMI cables for a display, and a USB keyboard/mouse. Storage and accessories are usually not included, so plan to add them.

Does it have full-size HDMI like older Pis?

No. The Pi 4 switched to two micro-HDMI ports to support dual displays. You will need micro-HDMI to HDMI cables or adapters, which is a common point people miss when upgrading from a Pi 3.
