If you want a single-board computer then you need a Raspberry Pi. They became the gold standard for a reason. The new generation improves performance in a number of ways, but the most important features are the powerful processor and GPU, the increased RAM, the inclusion of USB-3 ports, the dual micro-HDMI ports and the support for 4K displays.
At just 3.7 x 3 x 1.1 inches and 2.4 ounces, the tiny powerful desktop computer can fit easily in your pocket for on-the-go computing. The board can even take a few knocks around a bag, but it’s recommended that you wrap it in a case to protect the pins. The Raspberry Pi 4 is a great little gift for anyone interested in computing, particularly making their own computers. Check price on Raspberry Pi!
