Raspberry Pi 4 Introduction using python
- 2. •Raspberry Pi is a tiny (about 9x6cm), low-cost ($35+), single-board computer that supports embedded Linux operating systems •The recommended Operating System is called Raspberry Pi OS (Linux based)
- 3. • The Raspberry Pi is a small computer that can do lots of things • It has a small footprint (about 9x6cm) and it is cheap ($35+) • You plug it into a monitor and attach a keyboard and mouse • It has so-called GPIO pins (General Purpose Input/Output) for connection sensors and other electronic components like LEDs, etc. • Raspberry Pi is as well suited for prototyping, datalogging and different electronics projects, a media center, etc. • It can be used to learn programming, IT and other technical skills, etc. • RP has limited power (CPU, RAM, etc.) so it cannot normally replace a desktop computer or laptop for ordinary use • The “Hardrive” is a Micro SD card

- 5. Specifications of Raspberry Pi 4 Include: It has a 64bit quad-core processor having cortex-A72 (ARM v8) clocked @1.5GHz. The new Pi board includes Broadcom BCM2711 VC6 GPU able to handle two 4kp30 displays also it can handle H.265 decoding at 4kp60. It has two micro HDMI ports. Now the new Pi board comes in 2GB, 4GB, and 8GB LPDDR-4 RAM options. It has a dual-band 2.4/5.0 GHz Wi-Fi, Bluetooth 5.0, Gigabit Ethernet Port, 2 USB 3.0, and 2 USB 2.0 ports. USB type C power input port. Also, it has POE capability via separate POE HAT (add-on). It has a standard 40 pin GPIO header (having backward compatibility)
- 7. The Processor of Raspberry Pi 4: • Pi has a more powerful quad-core Cortex-A72 64-bit CPU running at 1.5GHz and Broadcom VideoCore VI GPU running at 0.5GHz. It can handle 4k videos, H.265 encoding 2 HDMI outputs. It has a fully functional Gigabit Ethernet interface and USB 3.0 port.
- 8. RAM Memory: • The new Raspberry Pi 4 comes with an option of 2GB, 4GB, and 8GB of RAM options. It has LPDDR4 RAM. Also, you get a heat sink for the RAM chip as it gets hot while operating.
- 9. Ethernet Controller: This Pi board has a Broadcom BCM54213 Gigabit ethernet controller. It falls to a slower speed if the network speed is slow. •Software-driven router •Media server •A bridge between Wi-Fi and Ethernet networks
- 10. USB Controller: • VL805 chip is the USB port controller for Raspberry Pi 4. • The Pi has 2 x USB 3.0 and 2 x USB 2.0 ports. • VL805 chip is a USB 3.0 Host controller. • it allows the PCI Express platform to interface with USB Super-Speed (5 Gbps), High-Speed (480 Mbps), Full- Speed (12 Mbps), and Low-Speed (1.5 Mbps) devices. • The root hub is consists of four downstream facing ports, it enables simultaneous operation of multiple peripheral devices.
- 11. Power Circuitry: • The Pi4 uses the MXL7704 it was developed specifically for Raspberry. • This chip reduced the complexity of the Pi board and also delivers more power to all the peripheral to run at more power. • Due to this chip cost of the board has also been reduced as the number of components has been reduced.
- 13. • Raspberry Pi • Micro SD Card (+ Adapter) • Power Supply • microHDMI to HDMI Cable • Monitor • Mouse • Keyboard What Do You Need?
