Raspberry Pi Zero, The Tiny Pi that is Changing the Electronics Industry

There is a reason why suppliers often tend to limit the amount of raspberry pi Zero gadgets that a single person can buy. Even in this price-plummeting era of electronics that are mass-produced, there is literally no electronic product that you can purchase for 10 USD that offers as much as the raspberry pi zero. Moreover, demand for the raspberry zero can quite easily outweigh production leading to unsatisfied customers. But what makes this device popular? Which features does the raspberry pi zero have? Is the raspberry pi zero as or more efficient than other raspberry pi versions? And should you consider purchasing a raspberry pi zero?

Raspberry Pi in a Nutshell

Raspberry pi PCBs (printed circuit boards) are unique circuit boards. Moreover, raspberry pi devices come in many different variations, which include the popular raspberry pi zero.

Typically, raspberry pi PCBs are a series of comps designed by the raspberry pi company. Moreover, these devices utilize a special type of circuit board known as a raspberry pi printed circuit board.

The Connections between Raspberry Pi and Printed Circuit Boards

Printed circuit boards are sheets of insulating components, for example, fiberglass, which has metallic tracks or circuits etched or printed onto them for efficient electrical conductivity. Moreover, printed circuit boards are found in most electronic products such as satellites, airplanes, military weapons, mouse, keyboards, laptops, computers, TV, Tablets, mobile phones, et cetera.

On the other hand, raspberry pi circuit boards are circuit boards that have a combo of castellated holes and through holes with pitch pin headers. Typically, Raspberry pi circuit boards are computer circuit board that features credit card sizes. Therefore, their size is ideal in terms of carrying out various tasks. Moreover, though compact, raspberry pi devices can carry out complex tasks such as:

  • Executing games

  • Generating spreadsheets

Raspberry pi devices are generated by the raspberry pi company. Moreover, this tech has been around since 2012.

Raspberry pi gadgets were developed to help improve the following:

  • Learning
  • Innovation
  • Experimentation

Moreover, raspberry pi circuit boards are portable PCBs available on all raspberry computers. Most raspberry pi circuit boards available in the market today are installed in mobile phones.

As per classifications, raspberry Pi circuit boards can be classified into two categories according to the model type. These raspberry models are model A and model B:

Model A

Model A Pi circuit boards utilize less power during operation. Moreover, these raspberry pi PCBs don’t feature Ethernet ports.

Model B

Model B pi circuit board, on the other hand, consumes more power during operations. Moreover, they also have Ethernet ports for wired WiFi connections and LAN connections.

Lastly, raspberry pi devices are open source. Therefore you can customize them to meet your desired needs.

The Raspberry Pi Zero


Even though the raspberry pi zero is efficient, the first thing that will strike you by surprise is how much it costs. Before you even move on to the specs of the pi zero, how to set it up, and the many different ways that you can utilize these devices, you will have to first thank the manufacturers of the raspberry pi zero for generating a 5 USD 32-bit desktop computer that can support a Linux operating system.

Of course, by trying to cut costs, the company might have compromised a bit on performance, where for example, you will find that these pi devices take longer to boot. However, when you purchase the raspberry pi zero circuit board, the part you get will only cost you 5 USD. To make it run efficiently, however, you will have to add other components to the board. However, the additional commodities are simple parts you might already have at home.

The Size of the Raspberry Pi Zero

After the price, the next thing that will surprise you is the size of the raspberry pi zero. On average, the raspberry pi zero measures 6.5 cm x 3cm. Moreover, this device is only 0.5cm thick, and its thickness mostly comes due to the various connectors embedded into the circuit board, such as the mini HDMI connectors.

The original model of the raspberry pi series is heavily utilized in many different applications. However, these raspberry pi circuit boards were relatively larger and mostly looked unwieldy or clunky when integrated into a robot or other intelligent projects. On the other hand, the popular raspberry pi zero is elegant and slim, and due to its small size, it can be utilized in many projects.

Specifications of the Raspberry Pi Zero

The raspberry pi is a power device that bears the following specifications:


The raspberry pi zero runs on a one gigahertz ARM 11 Broadcom central processing unit. Moreover, like most raspberry pi devices, this pi circuit board runs on a Videocore IV graphical user interface.

Memory and Storage

As per storage, the raspberry pi zero has a slot for microSD that you can utilize to host your operating system. Moreover, the device also comes with 512 MBs worth of memory to get you running.


When it comes to connectivity, the raspberry pi zero has the features:

Operating System and Connectors

The raspberry pi zero runs on a Linux operating system. Moreover, this pi circuit board comes bearing the following connectors:

  • 12C
  • SPI
  • Unpopulated 40-pin GP-Input/Output header


Even though the raspberry pi circuit board is efficient and comes bearing multiple features that make it stand out, it also features an astonishingly low retail price of around 5 to 4 USD.


When it comes to the design of the raspberry pi zero, there is no sugarcoating this. You get a printed circuit board design, nothing else. But for 5 USD, you can’t really complain about not getting any type of casing that most consumer-level electronic products come bearing. But this is beside the point; that’s because the raspberry pi zero is meant to be extremely cheap, raw, versatile, and cheerful so that professionals and hobbyists alike can explore the limits of this gadget.

However, for the raspberry pi company to achieve the target price and size, they had to cut off some features on pi zero, which are present on pi 1 and 2.

At first glance, the first thing that you will most probably note is that the SoC is near the center of the circuit board. Moreover, the board’s ports are at the bottom part of the circuit board.

The raspberry pi zero circuit board also has a single mini HDMI port which you can utilize to connect the board to a display. Moreover, the board also comes bearing two micro-USB ports which function as follows:

  • One is for power
  • The other is for data, or simply useful for normal micro-USB functions.

A close look at the micro-USB ports

To utilize these micro-USB ports to integrate various peripherals, for example, a mouse or a keyboard, into the circuit board, you will require a USB A female to micro-USB B male adapter.

However, another thing you will note about the design is that it misses Ethernet ports. Therefore, the lack of Ethernet ports means you cannot connect this pi circuit board to the internet or a network without adding USB Ethernet ports or WiFi USB dongles.

On the left side of the circuit board, you will note that the raspberry pi zero contains a microSD slot. However, these pi device lacks built-in flash memory like the pi two and pi 1; therefore, after purchasing the pi zero, you will have to buy a microSD card that will host the board’s operating system and store data.


After purchasing the raspberry pi zero, you get multiple hardware components functioning in unison to make the pi zero efficient. One of the main hardware components you will get will be a fully functional 32-bit Comp that runs on a one gigahertz ARMv6 microprocessor (single core. Moreover, you also get a working videoCore four GPU plus 512 megabytes of memory.

The board’s GPU has the ability to drive a full High Definition (HD) display at around 60 fps. Moreover, on top of getting RAM and SoC, the pi zero also comes bearing 40 GPIO ports that you can utilize to execute various connections. These 40 GPIO ports are the forty-plated holes that you will find on the top side of the board. However, you should note that the ports are unpopulated, meaning they do not have pins. Moreover, these headers are compatible with raspberry pi two and pi one versions. However, since they do not have pins, to utilize this header, you will have to solder the cables to the holes.

Due to their size and energy efficiency, the raspberry pi zero circuit boards can run on an external battery, making them efficient in portability. Moreover, their portability and size make them the perfect raspberry pi boards to use on robotic projects. Furthermore, they are also great portable computers because you will only need to carry the board, a batter, and a WiFi dongle, and that is it. You have a working Linux PC.


When it comes to making raspberry pi circuit boards cheaper, smaller, and faster, we give credit to the raspberry company for doing a great job. However, in terms of eliminating faults that make the raspberry pi less efficient in terms of performance, you will note that the company hasn’t done an excellent job. That is because, even though pi zero is efficient, it still carries forward the weaknesses of the original raspberry pi. However, despite these downsides, the raspberry pi is still pretty efficient and fast. Therefore, if you are looking to purchase one, we recommend you go for it.
