I usually get an 8GB microSD card but depending on the project I've gone larger. I like the SanDisk Extreme microSDHC UHS-I.
Make sure you have the proper power supply for the Pi 3. I believe it needs to be at least 2.5 amps.
Download the NOOBS zip file from the Raspberry Pi .org site and unzip its contents into the microSD card from your PC. The cards I buy are preformatted FAT32 which works fine for NOOBS.
Slip the microSD card into the Pi 3 and boot it up. If you press the w key you can connect to your home wifi network in order to view the complete list of installation options. You need to do this so you can select the Lite version of the Raspbian OS, which is my preference.
After the installation is completed and the Pi has rebooted, log in as user pi with password raspberry.
Change the root password to raspberry so you don't forget it (in case you need to su)
sudo passwd root
Go through the locale & internationalization options in raspi-config to set your timezone, keyboard, country, etc.
sudo raspi-config
Configure wpa_supplicant.conf so the Pi connects to your home wifi network on boot:
Setting WiFi up via the command line
Reboot the Pi:
sudo reboot
Update the Pi:
sudo apt-get update
sudo apt-get upgrade
Here's another way to change the keyboard configuration to US (the Pi defaults to a UK configuration):
sudo dpkg-reconfigure keyboard-configuration
Edit /etc/rsyslog.conf:
sudo nano /etc/rsyslog.conf
Comment out these lines at the bottom:
#daemon.*;mail.*;\ # news.err;\ # *.=debug;*.=info;\ # *.=notice;*.=warn |/dev/xconsoleSet the timezone of the Pi. Run the next command from the console rather than over SSH:
sudo dpkg-reconfigure tzdata
Older Pi kernel versions defaulted power management to on which in conjunction with another setting may result in the integrated wifi interface going to sleep - most inconvenient when trying to manage the prop over wifi!
The apt-get update and upgrade steps performed above should upgrade the kernel. You can check your kernel version by issuing the following command:
sudo uname -a
As of this writing my kernel version is 4.4.34-v7+ #930 SMP.
You can check the power save mode of the wifi interface using the following command:
sudo iw wlan0 get power_save
If it says power save mode is On then you can try adding this line to /etc/network/interfaces after the wlan0 section:
post-up iw wlan0 set power_save off
Then reboot and check the power save mode of the interface again to confirm it is now off. If you ever see this mode change back to On try searching the internet to solutions for the power management issue and try different solutions until it is resolved. Following the above steps resolved the issue for me.
