1. Rematadoview

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.
