Types of Arduino modules – original PCBs made by Italian manufacturer

If you are looking for a wide range of Arduino modules, you've come to the right place!

We have the most popular printed circuit boards that every enthusiast of programmable electronics knows well!

First of all, we recommend you Arduino UNO R3 (R3 – means the third, latest version). On this board we will find an 8-bit microcontroller, e.g. AVR ATmega328P, and pins leading to connectors for overlays (Arduino Shields), which can be bought later and easily added to the main board. Arduino Mega 2560 and Arduino Pro Mini (very small dimensions) and Arduino Nano (uses Atmega 168 and Atmega 328p microcontrollers) are other most popular products.

Also noteworthy are the Arduino main modules equipped with fast ARM processors (e.g. Arduino DUE ARM Cortex with the 84-MHz AT91SAM3X8E processor) and radio communication modules, e.g. the new Arduino Yun or Arduino MKR1000 ABX00004 with ATSAMW25 chip and integrated WiFi module WINC1500).

Beginners of electronics are advised to buy the Arduino UNO starter kit, but we guarantee that it will not be your last purchase. Arduino can be really engaging!

Arduino – reliable substitutes

Since the creation of Arduino programmable electronics with easy IDE software many different types of substitutes have been created. You can find various products on the internet, but unfortunately many of them will not work properly with Arduino original boards. Instead of buying unproven products, it is worth to choose verified counterparts that are reliable.

In this category we present both original PCBs and modules as well as proven counterparts. Many of these products have amazing features and conveniences. See for yourself. Check out the great Pololu A-Star 32U4 Prime LV kit with full expansion slot for microSD memory cards and the Atmega32u4 microcontroller. The power supply technique is unique in this model –Pololu A-Star 32U4 Prime LV can be powered by a very wide voltage range (2.7 V - 11.8 V). Other boards are also noteworthy, e.g. Bluno Beetle (Bluetooth 4.0 LE module and Atmega328 microcontroller included).

Programmable robot controllers compatible with Arduino IDE

Obviously no one would like to have no control over a robot built by himself. However, programmable robot controllers are these kind of electronics that allow you not only the control, but extend the possibilities of any machine. In this category you can see the full software & hardware compatible programmable robot controllers that work great with Arduino IDE boards.

Once again we can recommend you the products made by Pololu – one of the leading company on the robotics market. Zumo 32u4 motherboard with AVR microcontroller, integrated DC motor drivers and LCD display is a ready to use robot controller. The board can be programmed the way you want. Examples? Here you go! All you have to do is to add external drive mechanics to the system, and you will be able to create a robot that can move well on the ground. From this idea it is just a little step to create your own remote car or... a mobile vacuum cleaner. Why not?

The great advantage of all parts of the programmable electronics presented in Botland is the fact that the most depends on your own imagination.
