“The beetle is a surprisingly versatile beast sporting a respectable number of I/O as well as all communication protocols supported by the Atmel chip at its core. I have had a great deal of success assembling a variety of projects built around it and using the optional custom mini shield let you connect actuators/sensors without fuss.
It really is a must-have compact 'Arduino' that I have yet to outgrow and its size and price make it my to-go board. The inexpensive IO shield is the icing on the cake and will help you hit the ground running, I can't recommend it enough!”
