The Raspberry Pi 4 Model B is a versatile single-board computer designed for a wide range of applications, from desktop computing to embedded projects. It features a powerful Broadcom BCM2711 Quad-core Cortex-A72 (ARM v8) 64-bit SoC running at 1.5GHz, offering enhanced processor speed, multimedia performance, memory, and connectivity compared to previous generations. This model comes with 1GB of LPDDR4-2400 SDRAM.

Key features include 2.4 GHz and 5.0 GHz IEEE 802.11ac wireless, Bluetooth 5.0, BLE, Gigabit Ethernet, two USB 3.0 ports, and two USB 2.0 ports. It also provides two micro-HDMI ports supporting up to 4Kp60, a 2-lane MIPI DSI display port, a 2-lane MIPI CSI camera port, and a 4-pole stereo audio and composite video port. Hardware video decoding (H.265 4Kp60, H.264 1080p60) and encoding (H.264 1080p30) are supported, along with OpenGL ES 3.0 graphics.

The device utilizes a Micro-SD card slot for operating system loading and data storage. Power is supplied via a 5V DC USB-C connector (minimum 3A) or via the GPIO header (minimum 3A). Power over Ethernet (PoE) is also supported with a separate PoE HAT.

4. ຕັ້ງຄ່າ

The Raspberry Pi 4 Model B is designed for ease of use. This unit comes with a Samsung 32GB SD Card pre-loaded with Raspbian Buster (September 2019 update), requiring no initial setup for the operating system.

4.1 ການເຊື່ອມຕໍ່ເບື້ອງຕົ້ນ

1. ໃສ່ Micro-SD Card: Gently insert the pre-loaded Samsung 32GB Micro-SD card into the Micro-SD card slot on the underside of the Raspberry Pi board until it clicks into place.
2. ເຊື່ອມຕໍ່ຈໍສະແດງຜົນ: Connect one or two micro-HDMI cables from the Raspberry Pi to your monitor(s).
3. ເຊື່ອມຕໍ່ອຸປະກອນຕໍ່ພ່ວງ: ສຽບແປ້ນພິມ ແລະເມົາສ໌ USB ຂອງທ່ານໃສ່ພອດ USB ທີ່ມີຢູ່.
4. ເຊື່ອມຕໍ່ເຄືອຂ່າຍ (ທາງເລືອກ): For wired internet access, connect an Ethernet cable to the Gigabit Ethernet port. Wi-Fi is also available.
5. ເຊື່ອມຕໍ່ພະລັງງານ: Plug the 5V DC USB-C power supply (minimum 3A, not included) into the USB-C power input port. The Raspberry Pi will automatically power on and begin booting.

4.2 First Boot

Upon connecting power, the Raspberry Pi will boot directly into the Raspbian Buster desktop environment. Follow any on-screen prompts for initial configuration, such as setting your locale and password.

5. ລະບົບປະຕິບັດການ

The recommended operating system for the Raspberry Pi is Raspbian, a Debian-based OS optimized for the Raspberry Pi hardware. Your included SD card comes with Raspbian Buster pre-installed.

5.1 ການນຳໃຊ້ພື້ນຖານ

Once booted, you can interact with Raspbian Buster like any other desktop operating system. It includes a web browser, office suite, programming tools, and various utilities. Updates can be performed via the terminal using standard Debian commands (sudo apt update ແລະ sudo apt upgrade).
