What’s the Raspberry Pi ?
The Raspberry Pi, also called RPi, is a small open source mono-board computer used to prototype, or as rescue computer which cost less than 40€ for the last version. The conception began in 2006 with a first open source prototype. Currently, the Raspberry Pi is totally open source and the board’s plan is public.
The Raspberry Pi is often bought alone. To help you start with the Pi we’ve made a little list of the first devices you’ll need :
- Keyboard and Mouse
- Power supply ( 5V and 700mA is what we recommend at least )
- micro SD card ( class 10 recommended and at least 4GB )
- Screen ( HDMI compatible )
- HDMI cable
It’s a computer! Really tiny, but still a computer. A lot of distributions exists they are often based on linux kernel. You can find the most used distros here
Most of the time we’ll use SSH to configure our Pi. to do so plug in the basics peripherals. (keyboard, mouse, screen and of course power supply).
Enable SSH, it might be a diferent operation depending on the distros you’ve choosen.
And finally connect to your RPi with a SSH software such as PuTTy
You might have to get an additionnal Wi-Fi dongle depending of your RPi model
Rpi zero and RPi3 comes with a built-in Wi-Fi module.
The RPi is not really great looking, like all electronics board. But a lot of protection cases can be purchase pretty much anywhere, and if you don’t like them you can still design your own 🙂
For some project, you might need a camera, a touchscreen or any other peripherals, you can find all the official distributor on official RPi website.
My Raspberry Pi
My future RPi related articles will be writen for a Raspberry Pi 3B, but they can be applied on any other Raspberry Pi.
Here are characteristics of my particular board :
- Quad Core 1.2Ghz Boradcom BCM2837 64bit CPU
- 1GB RAM
- BCM43438 wireless LAN and Bluetooth Low Energy (BLE) on board
- 40-pin extended GPIO
4 USB 2.0 ports
4 Pole stereo output and composite video port
- Full size HDMI
- CSI camera port for connecting a Raspberry Pi camera
- DSI display port for connecting a Raspberry Pi touchscreen display
- Micro SD port to store and install your OS and data
- Upgraded switched Micro USB power source up to 2.5A
I only use my RPI for prototyping, but to create a real product, Raspberry Pi Zero is perfect, it has the same caracteristic only with a smaller size 🙂
