  • Funduino Leonardo is funduino team's new low-cost funduino controller. It has 20 digital I/o port, 7 PWM and 12 analog input port. Compared to other versions of funduino use separate USB to Serial conversion chip, Leonardo innovation adopted single chip solutions. Only a piece of Atmega 32u4 to achieve USB communication and control. This innovative design to reduce the cost of Leonardo. Atmega 32u4 original ecological support USB features can also make Leonardo simulation into a mouse and keyboard, greatly improve the applications. Using funduino Leonardo need the new version of the funduino IDE1.01 above.
