Raspberry Pi 4 Model B description
The speed and performance of the new Raspberry Pi 4 is a step up from earlier models. For the first time, we've built a complete desktop experience. Whether you're editing documents, browsing the web with a bunch of tabs open, juggling spreadsheets or drafting a presentation, you'll find the experience smooth and very recognizable — but on a smaller, more energy-efficient and much more cost-effective machine.
1.The fanless, energy-efficient Raspberry Pi runs silently and uses far less power than other computers.
2.Raspberry Pi 4 comes with Gigabit Ethernet, along with onboard wireless networking and Bluetooth.
3. new Raspberry Pi 4 has upgraded USB capacity: along with two USB 2 ports you'll find two USB 3 ports, which can transfer data up to ten times faster.
Broadcom BCM2711, Quad core Cortex-A72 (ARM v8) 64-bit SoC 1.5GHz
1GB, 2GB or 4GB LPDDR4-2400 SDRAM (depending on model)
2.4 GHz and 5.0 GHz IEEE 802.11ac wireless, Bluetooth 5.0, BLE
2 USB 3.0 ports; 2 USB 2.0 ports.
Raspberry Pi standard 40 pin GPIO header (fully backwards compatible with previous boards)
2 × micro-HDMI ports (up to 4kp60 supported)
2-lane MIPI DSI display port
2-lane MIPI CSI camera port
4-pole stereo audio and composite video port
H.265 (4kp60 decode), H264 (1080p60 decode, 1080p30 encode)
OpenGL ES 3.0 graphics
Micro-SD card slot for loading operating system and data storage
5V DC via USB-C connector (minimum 3A*)
5V DC via GPIO header (minimum 3A*)
Power over Ethernet (PoE) enabled (requires separate PoE HAT)
Operating temperature: 0 – 50 degrees C ambient
EU Power Adapter 5V 3A Type-C Power Supply
Adapter feature – Input: 100-240V 50/60Hz 0.3A; Output: 5V 3A;
Raspberry pi 4 generation power supply interface, type-C can be inserted both front and back side,it will not appear the issue of plugging reverse. Note: Raspberry PI 4 special power supply, could not support 3B+/3B!
Raspberry pi 4B has upgrade hardware, the overall power consumption function is imporve; The current is bigger than Raspberry pi 3B+, with 5V 3A adapter, can be support Raspberry pi 4B.
It included different of function, such as over power protection, over current protection, short circuit protection, over voltage protection, under voltage protection, electrostatic protection.
2GB Single: 1 x Raspberry Pi 4 Model B-2GB RAM
