The document provides an introduction to the Raspberry Pi, a small, low-cost computer developed by the Raspberry Pi Foundation to promote computer science education. It discusses the history and features of the Raspberry Pi, including different models such as the Raspberry Pi Zero W. The Raspberry Pi Zero W is well-suited for embedded Internet of Things projects due to its small size and integrated WiFi and Bluetooth connectivity, running on 512MB of RAM and requiring about 20mA of power.

2. Raspberry Pi
• The Raspberry Pi is a low cost, credit-card sized computer that
plugs into a computer monitor or TV, and uses a standarad
keyboard and mouse.

3. History
• The Raspberry Pi is a series of small single-board
• computers developed in the United Kingdom by the Raspberry
Pi Foundation to promote the teaching of basic computer
science in schools and in developing countries.

4. Why Raspberry Pi?
• very low cost (Rs 1550/- for Model A and Rs 2200/- for Model
B/B+.
• great tool for learning programming, computers and concepts of
embedded Linux, etc.
• supports and runs free and open source Linux OS.
• consume less than 5W of power.

5. There are different versions of raspberry
pi available as listed below:
• Raspberry Pi 1 Model A
• Raspberry Pi 1 Model A+
• Raspberry Pi 1 Model B
• Raspberry Pi 1 Model B+
• Raspberry Pi 2 Model B
• Raspberry Pi 3 Model B
• Raspberry Pi Zero

15. What is a Raspberry Pi zero W used for?
• The Raspberry Pi Zero W is ideal for making embedded Internet
of Things (IoT) projects.
• The Pi Zero W has been designed to be as flexible and
compact as possible with mini connectors and an unpopulated
40-pin GPIO, allowing you to use only what your project
requires.

16. Does Raspberry Pi zero W have WiFi?
• Raspberry Pi Zero W, which adds Wi-Fi and Bluetooth

17. How much RAM does a Raspberry Pi
zero W have?
• 512MB RAM
• The Raspberry Pi Zero and Raspberry Pi Zero W/WH are half
the size of a Model A+, with a 1GHz single-core CPU and
512MB RAM, and mini-HDMI and USB On-The-Go ports and a
camera connector.
• The Raspberry Pi Zero W also has integrated 802.11n wireless
LAN and Bluetooth 4.1.

18. How much power does a PI zero w use?
• Zero W requires about 20 mA

19. Technical Specifications
• 802.11 b/g/n wireless LAN
• Bluetooth 4.1
• Bluetooth Low Energy (BLE)
• 1GHz, single-core CPU
• 512MB RAM
• Mini HDMI and USB On-The-Go ports
