Raspberry Pi

Raspberry pi is normally called as small personal computer or mini-computer and this single board itself acts as a computer. USB Keyboard, USB Mouse and Monitor are connected as external devices to the Raspberry pi which will act as a Mini Pocket-sized personal computer. Below images shows Raspberry pi board.
Raspberry Pi has a lower config and specification than the Personal computer or Laptop but it is still a computer which can provide all the expected features or abilities at a low power consumption. The below image shows a structure on how to work like a computer using this raspberry pi board. In this below image, Monitor, Internet Router, Adapter, USB Keyboard, USB Mouse, etc., are connected externally.

More About Raspberry Pi

Important point to note is that it needs to have an SD card (minimum 8 GB recommended) to store the OS (operating System). Raspberry Pi is more than a computer as it provides access to the on-chip hardware i.e., GPIOs for developing an application. By accessing GPIO, we can connect devices like LED, motors, sensors, etc and can control them too. It is also popularly known for building a Real Time Operating system(RTOS) from Linux Platform and it also can be used for real time Image/Video Processing, IoT based applications and Robotic Application.
Raspbian OS is an official Operating System available for free to use. This OS is efficiently optimized to use with Raspberry Pi. Raspbian has a GUI which includes tools for Browsing, Python programming, office, games, etc. Raspberry Pi also provides on-chip SPI, I2C, I2S and UART modules. Raspberry Pi Foundation officially provides Debian based Raspbian OS. Also, they provide NOOBS OS for Raspberry Pi. We can also install several Third-Party versions of OS like Ubuntu, Arch Linux, RISC OS, Windows 10 IOT Core, etc.
It has ARM based Broadcom Processor SoC along with on-chip GPU (Graphics Processing Unit).
The CPU speed of Raspberry Pi varies from 700 MHz to 1.2 GHz. Also, it has on-board SDRAM that ranges from 256 MB to 1 GB.


There are different version 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 3 Model B+
  • Raspberry Pi Zero
  • Raspberry Pi 4

Raspberry Pi 3 On-chip Hardware

The On-chip hardware of Raspberry Pi 3 (here) is as shown in below figure
Some Internal / External Components shown above are mention below:
  1. Wireless/Bluetooth : It has come with inbuilt Wifi connection and a bluetooth setup automatically or manually with ease
  2. HDMI (High-Definition Multimedia Interface): It is used for transmitting uncompressed video or digital audio data to the Computer Monitor, Digital TV, etc. Generally, this HDMI port helps to connect Raspberry Pi to the Digital television.
  3. CSI Camera Interface: CSI (Camera Serial Interface) interface provides a connection in between Broadcom Processor and Pi camera. This interface provides electrical connections between two devices.
  4. DSI Display Interface: DSI (Display Serial Interface) Display Interface is used for connecting LCD to the Raspberry Pi using 15-pin ribbon cable. DSI provides a fast High-resolution display interface specifically used for sending video data directly from GPU to the LCD display.
  5. Composite Video and Audio Output: The composite Video and Audio output port carries video along with audio signal to the Audio/Video systems.
  6. Power LED: It is a RED colored LED which is used for Power indication. This LED will turn ON when Power is connected to the Raspberry Pi. It is connected to 5V directly and will start blinking whenever the supply voltage drops below 4.63V.
  7. ACT PWR:ACT PWR is Green LED which shows the SD card activity.

What People say about VAct Technologies

This place does 2 things, one is to develop new projects and the other is to train students to achieve a career at any one of the best top companies. I had seen this place on google maps and came here seeking a job. As a fresher, they gave me a test, and It was a bit easy to get some good marks. Next was a face-to-face interview process, which was also good. And since I had good knowledge of C and lacked experience in embedded systems. The company offered me free training to which I would gain knowledge just like a fresher getting trained in a placed company. It’s been 2 and half weeks since joining and have gained some knowledge on what is being done in the industry. If you’re looking for some training or if you want to shift to a new job, look no further “VACT technology” is the place to be.
