Kehitysalusta Raspberry Pi 4 Model B 1,5 MHz BCM2711 SC15185

Broadcom BCM2711 (4‑core Cortex‑A72 ARM v8, 1.5 GHz, 64‑bit SoC), 4 GB LPDDR4 RAM, WLAN, Bluetooth 5.0 BLE, 2 × USB 3.0, 2 × USB 2.0, 40‑pin GPIO, 2 × micro HDMI, Micro SD.

Raspberry Pi 4 is a compact development board offering a re‑engineered, faster platform suitable for desktop use, embedded systems and project prototyping. It preserves backward software compatibility so existing Raspberry Pi projects can be upgraded with minimal changes.

Advantages

The board provides increased processing performance compared with earlier Raspberry Pi models, enabling a complete desktop experience for everyday tasks while remaining fanless and energy efficient. Dual micro‑HDMI outputs support dual displays with 4K capability. Onboard Gigabit Ethernet, wireless LAN and Bluetooth 5.0 allow fast networking and peripheral connectivity. Two USB 3.0 ports deliver higher‑speed data transfers alongside two USB 2.0 ports. The 40‑pin GPIO header enables hardware interfacing and expansion.

Suitable for

• Desktop computing for web browsing, document editing and office applications
• Media centres and dual‑display video playback (up to 4K)
• Home automation and smart‑home hubs
• Embedded and robotics projects using GPIO
• Networked services and lightweight server tasks

How to use

Insert a compatible micro SD card preloaded with a Raspberry Pi OS or other supported operating system, connect power, displays (via micro‑HDMI), network and any USB peripherals. Configure initial system settings through the desktop interface or via command line. Use the GPIO header for connecting sensors, actuators or HATs following manufacturer wiring diagrams and safety guidelines.

Recommendations

Use a stable 5V USB‑C power supply that meets Raspberry Pi 4 power requirements, a correctly imaged and safely ejected micro SD card, and heat management if running sustained high‑load tasks. Verify OS and firmware updates for compatibility with connected hardware and accessories.
