Raspberry Pi 4 Model-B with 4 GB RAM

The Raspberry Pi 4 Model B with 4 GB RAM is a popular single-board computer (SBC) from the Raspberry Pi Foundation. It offers significant improvements over its predecessors in terms of performance, connectivity, and versatility, making it suitable for a wide range of applications, from basic computing tasks to more demanding projects like media centers, home automation, and even light server use.

Key Features:

• 4 GB of RAM: The 4 GB version of the Raspberry Pi 4 offers enough memory for multitasking and running more resource-intensive applications, such as web browsing, word processing, and light programming.

• Processor: Broadcom BCM2711: A quad-core ARM Cortex-A72 CPU clocked at 1.5 GHz, providing much better performance than earlier models (especially when it comes to multi-core tasks).

• Connectivity:

  • USB Ports: 2 × USB 3.0, 2 × USB 2.0 ports for connecting peripherals.
  • Gigabit Ethernet: For faster wired networking.
  • Dual HDMI Outputs: Supports 2 × micro HDMI ports with up to 4K resolution (1 × 4K @ 60Hz or 2 × 4K @ 30Hz).
  • Wi-Fi: 2.4 GHz and 5 GHz IEEE 802.11ac Wi-Fi.
  • Bluetooth: Bluetooth 5.0 for connecting wireless devices.

• Storage:

  • MicroSD Slot: For booting the OS and storing data.
  • USB Booting: The Raspberry Pi 4 can boot from USB drives, allowing for faster storage options compared to microSD cards.

• Graphics:

  • VideoCore VI Graphics: Provides good support for 3D graphics and video playback, making it ideal for multimedia applications.

• Power Supply: Requires a 5V/3A USB-C power supply, offering better power management compared to earlier models.

• GPIO Pins: 40-pin GPIO header for connecting sensors, actuators, and other hardware components in various DIY and hardware projects.
