Leonardo Arduino R3 (with 50cm USB cable) Electronic Components Electronic Hobby Kit

Arduino Leonardo R3 (with usb cable) One of the few Arduino boards that utilizes a single microprocessor for programming, USB-UART connectivity, and user code is the Arduino Leonardo R3. Its single processor, the ATmega32U4, enables simpler and less expensive hardware. Additionally, code libraries that enable the board to imitate a computer keyboard, mouse, and other devices via the USB-HID protocol are available because the ATmega32U4 is managing the USB directly. There is 100% compatibility between this clone and the original Arduino Leonardo R3. Specifications: Microcontroller: ATmega32u4 Operating Voltage：5V Input Voltage (Recommended): 7-12V Input Voltage (Limits): 6-20V Digital I/O Pins: 20 PWM Channels: 7 Analog Input Pins: 12 DC Current per I/O Pin: 40mA DC Current for 3.3V Pin: 50mA Flash Memory: 32kB of which 4kB used by bootloader SRAM: 2.5kB EEPROM: 1kB
