Raspberry Pi
is a credit-card sized computer that plugs into a computer monitor or
TV and uses a standard keyboard and mouse. We all are familiar with Raspberry Pi 1 and Raspberry 2 models. There is no wonder if I say that there are huge fans for Raspberry models. Raspberry satisfied many users with its 1GB Ram, Ethernet port, Micro SD storage, Audio jack 3.5mm port etc.
It gained a huge success in the market as it available at $35 so that
it can be affordable by most of the people. The main aim behind its
launch is to enable people of all ages to explore computing and to learn
how to program in languages. It has been used in a wide array of
digital maker projects, from music machines and parent detectors to
weather stations and tweeting birdhouses with infra-red cameras.
The main drawback of Raspberry Pi 2 is that it lacks WiFi and Bluetooth.Raspberry Pi 3 comes with the additional features like WiFi and Bluetooth. It also has a fast processor compared to the previous model. Previously, you needed to shell out around $10 for a USB Wi-Fi adapter. And also you need to waste a lot of USB storage place for Bluetooth dongles. And also speed has enhanced by upgrading 900MHz Quad-core CPU with 1.2GHz 64-bit Quad-core. In this view, it is sure that Raspberry Pi3 not only comes with additional features but also at a lower cost i.e $35. Comparison between the 3 models is shown in the below figure.
The following are the features of Raspberry Pi-3:
- A 1.2GHz 64-bit quad-core ARMv8 CPU
- 802.11n Wireless LAN
- Bluetooth 4.1
- Bluetooth Low Energy (BLE1GB RAM)
- 1GB RAM
- 4 USB ports
- 40 GPIO pins
- Full HDMI port
- Ethernet port
- Combined 3.5mm audio jack and composite video
- Camera interface (CSI)
- Display interface (DSI)
- Micro SD card slot (now push-pull rather than push-push)
- VideoCore IV 3D graphics core
