Raspberry Pi 4 Model B unboxing

I had recently ordered my Raspberry Pi 4 Model B with 4GB RAM variant and it is here.

As the demand for the 4GB RAM variant was so high they actually got out of stock just within a day, hence DNA solutions asked me if I would like to get my hands on the 2GB RAM variant and after my confirmation they sent me the 2GB RAM variant so that I could do a Raspberry Pi 4 Model B unboxing for all of you guys as soon as possible. 

There are three variants of Raspberry Pi 4 Model B :

- Raspberry PI 4B 1GB RAM

- Raspberry PI 4B 2GB RAM 

- Raspberry PI 4B 4GB RAM 

Below are the links where you can buy Raspberry Pi 4 Model B online in India

Raspberry pi organisation has recently launched their latest Raspberry pi 4 model B. इस वीडियो में आपको Raspberry pi 4B के बेसिक स्पेसिफिकेशन बताऊंगा.
अभी तक मैंने भी Rpi 4B खरीदा नहीं है. मैं आपको Raspberry pi 4b की बेसिक जानकारी दूंगा और Raspberry pi 4b ऑनलाइन ऑर्डर भी करूंगा
Raspberry pi 4B Model is a very powerful and efficient at handling tasks as compared to the older raspberry pi3 and 3b plus models. It can completely work as a computer cpu because of its powerful 1.5 GHz 64-bit processor.
The Raspberry pi 4 model B comes in three Variants. The only difference in in all the three variants is the Ram Capacity.

Three variants of raspberry pi 4 model b are:
- Raspberry pi 4 model B 1GB Ram
- Raspberry pi 4 model B 2GB Ram
- Raspberry pi 4 model B 4GB Ram

Specifications of latest raspberry pi 4b are as follows:
1) A 1.5GHz quad-core 64-bit ARM Cortex-A72 CPU (~3× performance)
2) 1GB, 2GB, or 4GB of LPDDR4 SDRAM
3) Full-throughput Gigabit Ethernet
4) Dual-band 802.11ac wireless networking
5) Bluetooth 5.0
6) Two USB 3.0 and two USB 2.0 ports
7) Dual monitor support, at resolutions up to 4K
8) VideoCore VI graphics, supporting OpenGL ES 3.x
9) 4Kp60 hardware decode of HEVC video
10) Complete compatibility with earlier Raspberry Pi products

Make 11.1 v 5200mAH Battery bank at home | No soldering | Just in 5 minutes

Hey Guys I am Pawandeepsingh Dhingra and In this video I will be showing you how to make a 11.1 volt 5200 mAH battery pack using some lithium ion batteries. For this project we will also need a solder less battery pack kit using which we can connect batteries in series and parallel combination without spot welding and soldering.
