Sparkfun Raspberry Pi 4 Model B (4 GB)

The Raspberry Pi 4 Model B with 4GB DDR4 RAM transforms the compact, credit card-sized development platform into a full-fledged desktop experience. Equipped with dual micro HDMI ports, it supports two 4K monitors simultaneously and offers true Gigabit Ethernet for superior multimedia performance. With two USB 2.0 ports and two USB 3.0 ports, it ensures rapid data transfer, making it a versatile tool for various applications. Simply connect a monitor, keyboard, and mouse, load the latest Raspbian image onto a MicroSD card, and enjoy a complete desktop computer solution.

The Raspberry Pi 4 is ideal for a wide range of projects, from running Tensorflow for machine learning experiments to setting up a PiHole for ad-blocking, playing Minecraft, or using Kodi for media streaming. Its compact size and robust capabilities make it perfect for hobbyists and professionals alike, offering endless possibilities for innovation and creativity.

Retaining many features of its predecessor, the Raspberry Pi 3 B+, this model includes a 40-pin GPIO header for easy integration with other components. It supports dual-band 2.4/5.0 GHz WiFi and Bluetooth 5.0, ensuring seamless connectivity. The introduction of a USB Type-C connector for power delivery replaces the Mini-B connector, providing more efficient power management.

The Raspberry Pi 4 requires a suitable power supply to handle its increased power consumption compared to the Pi 3 B+. Additionally, Power over Ethernet (PoE) is achievable with the PoE HAT, expanding its versatility in networked environments. For those using third-party power supplies or running more demanding programs, proper power sources and heat dissipation measures are recommended to ensure optimal performance.
