Raspberry Pi 4 Model b – 4GB Ram

Raspberry Pi 4 Model B is the latest product in the popular Raspberry Pi range of computers. It offers ground-breaking increases in processor speed, multimedia performance, memory, and connectivity compared to the prior-generation Raspberry Pi 3 Model B+, while retaining backwards compatibility and similar power consumption. For the end user, Raspberry Pi 4 Model B provides desktop performance comparable to entry-level x86 PC systems.

This product’s key features include a high-performance 64-bit quad-core processor, dual-display support at resolutions up to 4K via a pair of micro-HDMI ports, hardware video decode at up to 4Kp60, 1GB RAM, dual-band 2.4/5.0 GHz wireless LAN, Bluetooth 5.0, Gigabit Ethernet, USB 3.0, and PoE capability (via a separate PoE HAT add-on).

Features:

• Silent, energy efficient Quad-Core 64-bit Broadcom 2711, Cortex A72 processor :Raspberry pi run silently and saves more energy compared to other computers as it uses 20% less power compared to its previous versions.

• RAM: Raspberry Pi 4 is now available with different versions depending on the Ram user needs. RAM options provided are 1 GB, 2 GB and 4 GB as per requirement.

• USB 3: New Pi computer has an upgraded USB capacity with two more USB 3 port to with 10 times more transfer speed.

• Fast networking: Raspberry Pi boards have gigabyte Ethernet, in addition to onboard wireless networking and Bluetooth.

• Power: Micro USB-B is upgraded to Micro USB-C power connector which supports extra 500mA of current.

• Dual Screen:Type-A HDMI cable is changed to pair of type-D HDMI connectors to enable dual monitor excess.
