DFRobot Beetle

Dette lille board fra DFRobot kommer med en AtMega32u4 clocket ved 16MHz, med 10 digitale pins, 5 analoge pins og 4 pwm pins. Kortet er nemt at programmere, da det kommer med et Micro-USB stik (vælg Arduino Leonardo i Arduino IDE'en).

Som en mini-udgave af Arduino Leonardo, kommer den med lignende kraftfulde funktioner. Dette kort er billigt og småt nok til at kunne bruges i permanente installationer hvor pladsen er trang.
