You may wonder what a Raspberry Pi board is. Well to put it simple, it’s a credit-card sized computer that plugs into a computer monitor or TV. It is also capable of doing everything a desktop computer could do, and useful to learn programming languages like Scratch and Python.
These are currently all the Raspberry Pi boards you can get:
Raspberry Pi 2 Model B
This Raspberry model, it’s the second generation of Raspberry Pi. And they are recommended for school work as it offers more flexibility for learners, very useful for projects that require very low power. These are the Raspberry Pi 2 Model B specs:
- A 900MHz quad-core ARM Cortex-A7 CPU
- 1GB RAM
- 4 USB ports
- 40 GPIO pins
- Full HDMI port
- Ethernet port
- Combined 3.5mm audio jack and composite video
- Camera interface (CSI)
- Display interface (DSI)
- Micro SD card slot
- VideoCore IV 3D graphics core
Because of its ARMv7 processor, it can work with ARM GNU/Linux distributions, Snappy Ubuntu Core, as well as Microsoft Windows 10.
Raspberry Pi 1 Model B+
This model, it’s based on the earlier one, except it comes with a bunch of upgrades which really makes it worthwhile. As the regular Model B, it’s suitable for schoolwork and has the same compatibility with a handy size.
- The GPIO header has grown to 40 pins, while retaining the same pinout for the first 26 pins as the Model B.
- This model has 4 USB 2.0 ports, compared to 2 on the Model B, and better hotplug and overcurrent behavior.
- The old friction-fit SD card socket has been replaced with a much nicer push-push micro SD version.
- Lower power consumption by between 0.5W and 1W.
- With better audio, the audio circuit incorporates a dedicated low-noise power supply.
- Neater form factor. They’ve aligned the USB connectors with the board edge, moved composite video onto the 3.5mm jack, and added four squarely-placed mounting holes.
Raspberry Pi 1 Model A+
The Model A+ it’s a lower cost variant from the Model B+, it retains most of its features, but it’s an important point to make that this particular model, it’s recommended for very low power embedded projects and projects that does not require Ethernet or multiple USB ports because the Raspberry Pi 1 Model A+ has a lesser quantity of USB ports in it.
Raspberry Pi Zero
The model Zero it’s a very useful board. From all Raspberry Pi boards, the Model Zero it’s a good deal considering is half the size of a Model A+, with twice the utility. Because of this, this model, it’s recommended for almost any project and affordable too! But you have to buy complete raspberry pi starter kit for all accessories. These are the specs of the Model Zero:
- 1Ghz, Single-core CPU
- 512MB RAM
- Mini HDMI and USB On-The-Go ports
- Micro USB power
- HAT-compatible 40-pin header
- Composite video and reset headers
