Cheap Arduino compatible boards are same as original

Probably you have noticed that Arduino is spread worldwide. It would be ridiculous to see one manufacturer producing them. The Arduino group produces original board that are named Arduino. This is their trademark. But being open source product, Arduino become popular popular in almost all workshops and so demand is huge. Since building plans are open other electronics manufacturers started building Arduino compatible boards. These are same Arduino boards, but with Arduino name and logo removed. Other than that is 100% compatible to standard Arduino that works with software tools, extensions and modules. Arduino compatible Uno R3 Rev3 development board is one of most known boards. Because this form factor is the first Arduino step in to community.

Arduino introduces new boards – Uno and Mega2560

Arduino is well known platform among electronics hobbyists because of its simplicity, robust and intuitive design and ease of use even for non electronics enthusiasts. This time instead of introducing new PCB variants or different microcontrollers on board they made some significant upgrades in Arduino concept. New changes came with two new Arduino boards so called Uno and Mega2560. Probably biggest change is USB to serial converter. They decided to replace seemed to be hard positioned FTDI chip FT232RL with microcontroller Atmega8U2 that has hardware USB interface. With this upgrade Arduino board become much more flexible as microcontroller driver can be configured to be more that simple USB to serial converter. It also is able to convert Arduino to standard keyboard, mouse, MIDI and mass storage device. So, there is much more ways to use Arduino now. But this is not over yet. Arduino decided to change bootloader too with…
