Raspberry Pi 3 Model B+

The Raspberry Pi 3 Model B+ is a popular single-board computer that offers a good balance between performance, connectivity, and price. It is part of the Raspberry Pi 3 series and was released as an upgrade to the Raspberry Pi 3 Model B, bringing several improvements, including better networking, enhanced CPU, and faster performance overall.

Features of the Raspberry Pi 3 Model B+:

1. Processor (CPU):

   • Broadcom BCM2837B0 quad-core ARM Cortex-A53 CPU, clocked at 1.4 GHz.
   • This provides a performance improvement over the previous 1.2 GHz version, making it suitable for a wider range of applications, including lightweight desktop computing, media centers, and DIY electronics.

2. Memory (RAM):

   • 1 GB LPDDR2 SDRAM (low power), which is sufficient for running lightweight operating systems like Raspberry Pi OS, Ubuntu, or even some lightweight desktop environments.

3. Networking:

   • Wi-Fi: Built-in 802.11n Wi-Fi for wireless networking.
   • Ethernet: Gigabit Ethernet over USB 2.0 (up to 300 Mbps).
   • Bluetooth: Bluetooth 4.2 (BLE support), allowing you to connect Bluetooth peripherals like keyboards, mice, and speakers.

4. USB Ports:

   • 4x USB 2.0 ports for connecting peripherals like USB storage devices, keyboards, and mice.

5. Video Output:

   • HDMI Output: Full-size HDMI port for connecting to displays (supports 1080p at 60Hz).
   • Composite Video: Available through the 3.5mm AV jack for older TV connections.

6. Audio Output:

   • 3.5mm Audio Jack: For audio output (analog).
   • HDMI Audio: Audio can also be output through the HDMI cable.

7. Storage:

   • MicroSD card slot for storing the operating system and data. The microSD card is used as the primary storage, where the OS and files are kept.

8. GPIO (General Purpose Input/Output) Pins:

   • 40-pin GPIO header: Fully compatible with all Raspberry Pi accessories, shields, and HATs.
   • The GPIO pins allow you to interface with external sensors, motors, and other components for embedded projects, robotics, home automation, and more.

9. Power Supply:

   • 5V / 2.5A via micro-USB: The Raspberry Pi 3 Model B+ requires at least 2.5A to operate, especially when connecting multiple peripherals.
   • Power over Ethernet (PoE): Supported with an optional PoE HAT.

10. Camera Interface:

• Camera Serial Interface (CSI) port for connecting a Raspberry Pi Camera Module or other compatible camera.

11. Display Interface:

• Display Serial Interface (DSI) port for connecting a compatible touchscreen display.
