All devices need to be returned at the end of this course

Please take care of your Pi kit

Get Started Assemble the Pi (refer to the manual)

1. Take out the case and Pi board


2. Put Raspberry Pi into the case


3. (Optional) Put on the heat sinks and cooling fan Red wire on right 2nd pinBlack wire on right 3rd pin


4. Insert the SD card Micro SD Card Store your OS and data 32GB is enough for lab tasks Pre-installed with NOOBS

NOOBS is an easy operating system installer which includes Raspbian. It also provides a selection of alternative operating systems.
