Specification
Advantages
| UNO PLUS | UNO R3 | Remarks | |
| Operating voltage | 5V/3.3V | 5V | Dual voltage level to support more shields |
| Reset | Lateral | Vertical | Lateral button is easier to use when connecting with shield |
| Bootloader switch | Yes | None | The board can be configured to run program immediately when power-up by the switch |
| USB connector | Micro USB | USB Type B | Micro connector is more commonly used, and shields won't be blocked anymore while connecting |
| DC jack | Low profile | Normal height | Shields won't be blocked anymore while connecting |
| Power output header | Yes | None | Providing 5V/3.3V power output OR common-grounding with other boards |
| 3.3V power output | 800mA Max | 150mA Max | UNO PLUS features higher driving capability |
| Oscillator | Crystal oscillator | Ceramic resonator | Crystal oscillator is suit for applications where accurate clock reference is required |
| ADC channel | 7 | 6 | An additional channel ADC6 from the Reserved PIN |
| Connecting with prototype breadboard | Supported | Not supported | Solder pads is provided for DIY interfaces to connecting with prototype breadboard |
| USB driver | Compatible with all main systems | Doesn't compatible with WIN7/WIN8 Express Edition | Driver will never failed to install thanks to the onboard FT232 |
| Firmware fixing | Supported | Not supported | Firmware can be fixed by using the onboard FT232, no extra programmer is needed |
