Raspberry Pi 4 Model B -8GB RAM -Made in UK

Raspberry Pi 4 Model B -8GB RAM -Made in UK is a high-quality electronic component designed for Arduino, prototyping, and educational electronics. The Raspberry Pi 4 Model B (8 GB) is the latest product in the latest version within the Raspberry Pi range. The minicomputer offers improvements in processor speed, multimedia performance, memory, and connectivity compared to the previous generation Raspberry Pi 3 Model B + while maintaining backward compatibility and comparable power consumption. For the end user, Raspberry Pi 4 Model B offers desktop performance comparable to entry-level x86 PC systems.

The main features of this board are the powerful 64-bit quad-core processor, dual display support with resolutions up to 4K via 2 micro-HDMI ports, hardware video decoding up to 4Kp60, 8GB RAM, dual-band 2.4 / 5 .0 GHz wireless LAN, Bluetooth 5.0, Gigabit Ethernet, USB 3.0 and PoE capabilities (via a separate PoE HAT add-on). The dual-band wireless LAN and Bluetooth have a modular conformity certification, which allows the board to be designed into finished products with significantly less conformity testing.

Communication in Raspberry Pi 4
Raspberry Pi 4 has popular communication interfaces, available on traditional desktop and laptop computers. The most important of them are:

2 micro HDMI connectors to simultaneously connect two monitors up to

WiFi module – a 2.4 GHz and 5 GHz 802.11b/g/n/ac dual-band module.
Bluetooth 5 module – popular 5.0 standard wireless connectivity
2 USB 3.0 and 2 USB 2.0 connectors to connect peripheral devices. USB 3.0 allows for quick transfer from an external drive.
An Ethernet socket , which allows wired connection to the network at up to 1 Gb/s.

GPIO – 40 general-purpose output/input pins, used for LEDs, buttons, motor controllers, and interfaces: I2C, SPI, and UART interfaces.

Power supply for Raspberry in version 4 minicomputer
Raspberry Pi 4 needs a power supply with a USB C connector and an output voltage of 5 V. The minimum recommended current capacity is 3 A.
