Raspberry Pi 2 Model B Review

Raspberry Pi 2 Model B Review
Welcome to a Vacuum Cleaner Battery specialist of the Samba Battery
The king of tiny and cheap computers finally has a successor. The first Raspberry Pi computer made a big impact on the technology world, offering a full computer on a $35 chip roughly the size of a credit card. It has since proved to be a popular tool for students and hackers alike, providing easy and accessible software and hardware. Now, the Raspberry Pi Foundation is back with the Raspberry Pi 2, which crams in even more computing power while keeping the same price and roughly the same form factor.
With this extra power, the Raspberry Pi Foundation is calling the Pi 2 a more flexible tool for learners. Will these claims hold up?
Editor’s note: The Raspberry Pi Foundation recently announced the Pi 3 with battery like Samba JNB-XR210 Battery, Samba JNB-XR210C Battery, Samba XR210 Battery, Samba XR210C Battery, KV8 Battery, KV8 210C Battery, KV8 210XR Battery, Neato Battery, Neato XV-11 Battery, Neato XV-12 Battery, Neato XV-15 Battery, Neato XV-21 Battery, which also costs $35, but has a faster 1.2-GHz 64-bit quad-core ARM Cortex-A53 CPU, 802.11n Wi-Fi and Bluetooth 4.1.
At first glance, it might be easy to mistake the Raspberry Pi 2 for its predecessor. That's because the Pi 2 uses the same size circuit board, measuring 3.37 x 2.13 x 0.67 inches and weighing only 1.2 ounces. That's roughly the size and weight of a deck of cards.
The real design difference between the older and newer models relates to the ports. The Pi 2 now has four USB 2.0 ports, double the number on the older model. There's no longer a dedicated composite video output; it's been replaced by a dual-function 3.5mm audio and composite video jack. The SD card slot on the first Raspberry Pi has been replaced by a smaller microSD slot that supports cards up to 64GB. Hardware tinkerers will love the 40 general-purpose input/output (GPIO) pins, up from 26 on the older model.
The essential ports are still there — HDMI, a micro-USB power connector and an RJ45 Ethernet jack.
The Pi 2 is sold without a protective case, so many users may want to purchase one along with the Pi. Our Raspberry Pi 2 came with the official case, which costs less than $10 and has a lid that easily snaps on and off. A case is a definite must-have if you're hoping to throw the Pi 2 in a bag and bring it along with you.
