Understanding the function of each component is essential for a successful build.

• Display: The display is arguably the most crucial component of a tablet. It's your primary interface for interacting with the device. Tablet displays typically use LCD (Liquid Crystal Display) or OLED (Organic Light-Emitting Diode) technology. LCDs are generally more affordable and offer good brightness, while OLEDs provide superior contrast, deeper blacks, and wider viewing angles. Resolution is another critical factor; higher resolutions result in sharper, more detailed images. Touchscreen functionality is essential for a tablet, and most displays incorporate capacitive touch technology for accurate and responsive input.

• Processing Unit (CPU): The CPU is the brain of the tablet, responsible for executing instructions and performing calculations. Tablet CPUs are typically based on ARM architecture, which is known for its energy efficiency and performance. Popular ARM CPU manufacturers include Qualcomm (Snapdragon), MediaTek, and Samsung (Exynos). When selecting a CPU, consider its core count, clock speed, and power consumption. More cores and higher clock speeds generally translate to faster performance, but also higher power consumption.

• Graphics Processing Unit (GPU): The GPU handles the rendering of images, videos, and user interfaces. It's crucial for gaming, video playback, and other graphically intensive tasks. Many ARM CPUs integrate a GPU directly into the chip (an integrated GPU). Standalone GPUs are less common in tablets due to power consumption and space constraints, but they can offer significantly improved graphics performance.

• Memory (RAM): RAM (Random Access Memory) is temporary storage that the CPU uses to hold data and instructions that are currently being used. More RAM allows the tablet to run more apps simultaneously without slowing down. A minimum of 4GB of RAM is recommended for a modern tablet, and 8GB or more is preferable for demanding tasks.

• Storage: Storage is where you store your operating system, apps, files, and other data. Tablets typically use solid-state storage (SSD) in the form of eMMC (embedded MultiMediaCard) or UFS (Universal Flash Storage). SSDs offer faster read and write speeds compared to traditional hard drives, resulting in quicker boot times and app loading. The amount of storage you need depends on your usage habits, but 64GB is a reasonable starting point, and 128GB or 256GB is preferable for storing large files or installing many apps.

• Battery: Battery life is a critical consideration for any portable device. Tablet batteries are typically lithium-ion or lithium-polymer. Battery capacity is measured in milliampere-hours (mAh). A larger mAh rating generally translates to longer battery life. When selecting a battery, consider its size, voltage, and discharge rate.

• Motherboard/Development Board: In the context of a DIY tablet, the "motherboard" is often a single-board computer (SBC) or a development board. These boards integrate the CPU, GPU, RAM, and essential I/O interfaces onto a single circuit board. Popular options include Raspberry Pi boards, Rock Pi boards, and similar offerings from other manufacturers. These boards provide a platform for running the operating system and connecting other components.

• Power Management System (PMS): A PMS is essential for regulating the flow of power to the various components of the tablet. It ensures that the battery is charged safely and efficiently and that the tablet receives a stable power supply.

• Connectivity: Tablets typically include Wi-Fi and Bluetooth connectivity for wireless networking and peripheral connections. Some tablets also include cellular connectivity (3G, 4G, or 5G) for mobile internet access.

• Enclosure: The enclosure is the physical case that houses all the components of the tablet. It provides protection from damage and contributes to the overall aesthetic of the device. You can either purchase a pre-made enclosure or design and 3D-print your own custom enclosure.

• Operating System (OS): The operating system is the software that manages the hardware and provides a user interface for interacting with the tablet. The most common operating systems for tablets are Android and Linux. Android is a popular choice due to its wide range of apps and its open-source nature. Linux offers more flexibility and customization options but may require more technical expertise to set up.

The history of tablet computing dates back much further than many realize. While modern tablets have exploded in popularity in recent decades, the concepts behind them have been around for half a century. Envisioned by Alan Kay in 1968, the Dynabook was a conceptual device designed to provide children with access to all of human knowledge. While not a physical product, the Dynabook outlined the key features of a modern tablet: a portable, interactive device with a graphical user interface. Early attempts at creating pen-based computing devices continued throughout the 1980s and 1990s, with devices like the GRidPad and Apple Newton paving the way for more advanced tablets. It wasn't until the launch of the Apple iPad in 2010 that the tablet market truly took off. The iPad's intuitive touchscreen interface, sleek design, and vast app ecosystem popularized the form factor and spurred competition from other manufacturers. Android tablets followed soon after, offering a wider range of price points and features. Today, tablets are used for a wide variety of purposes, from entertainment and communication to productivity and education.
