is kept to ensure people without any soldering experience can get it run with only

a little effort.

3. Compatible Microcontroller for Arduino

8 SQUARE features a classic Atmega328 as its processor. You can totally

reprogram it as anUNO - the most widely adapted board for now. Thousands

of tutorials and libraries over the community are easily to found when you need
