Arduino Leonardo R3 Price in Pakistan
The Arduino Leonardo R3 is based on the ATmega32U4 microcontroller. Unlike boards that use a separate USB-to-serial controller, the ATmega32U4 provides native USB communication. This allows compatible sketches to present the board to a computer as a keyboard, mouse or serial device.
Key specifications
- Microcontroller: ATmega32U4
- Operating voltage: 5V
- Recommended input voltage: 7V to 12V
- 20 digital input/output pins
- Seven PWM-capable outputs
- 12 analog input channels
- 32KB flash memory, 2.5KB SRAM and 1KB EEPROM
- 16MHz clock
- Native USB communication through the micro USB connection
Suitable applications
- USB keyboard and mouse controller projects
- Custom USB interfaces
- Robotics, automation and sensor systems
- Educational programming and embedded prototypes
Compatibility guidance
The Leonardo differs from the UNO in its USB implementation and some pin assignments. Confirm shield pin use and library compatibility before assembly. Use a compatible micro USB data cable; a power-only cable cannot upload sketches.
For breadboard connections, pair the board with male-to-male jumper wires and a GL-12 solderless breadboard.
