5V 16 MHz ATmega32u4 Development Board with USB Cable for Leonardo R3 Pro

Features: 1. The development board has 20 digital input and output interfaces, 7 PWM interfaces and 12 analog input interfaces. 2. Using a separate USB-Serial converter chip compared to other versions, this product is innovative with a single-chip solution. Only piece of Atmega32u4 was used to implement USB communication and control. This innovative design reduces costs. 3. Atmega32u4\'s native support for USB features also allows the development board to be modeled as a mouse and keyboard, greatly improving the application. 4. A new version for Arduno IDE 1.01 or higher is required to use for Arduno Leonardo. 5. Easy to operate, anti-aging, prolong service life.
