Most of the Duinotech models use two chipsets, one for the main controller, one for USB communication. The Duinotech Leonardo combines both these functions into a single IC, which opens to door for more advanced USB functions. The development board also boasts more analogue inputs (12), and an extra PWM channel.
Features:
- Fully Arduino™ compatible
- ATMega32u4 microcontroller

- Built in USB-Serial
- IO:
Digital IO: 20 pins (7 are configurable as digital or PWM)
PWM Capable: 7 pins
Analogue Inputs: 12 pins (6 are shared with digital pins)
Serial Ports: 2 (One USB, one UART, more supported via SoftwareSerial library)
Input voltage:
- 5VDC Regulated via USB port or 5V pin
- 7-12VDC via vin pin
- On-board regulator supplies 5V when unit is powered via vin pin

Great Service, Board just as wanted
Bought this about two weeks ago, product was great and customer service was excellent as they helped me find everything I need (Reynella, 5161) Helped me breadboard a project and uses ATMega32u4 which has more features than something like an UNO (Still good, just needed something better)
Arduino Uno compatible mostly
Exactly the same footprint and most of the same capabilities as an Arduino Uno, except has direct control of the USB rather than via a chip. This means that while it pulls a bit more computational power to do so, you can get it to emulate a keyboard, mouse, controller, joystick, and more via code!
