The manufacturer has introduced several modifications that significantly improve the work with the R3 PLUS.
R3 PLUS | OFFICIAL 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 | R3 PLUS features higher driving capability |
Oscillator | Crystal oscillator | Ceramic resonator | Crystal oscillator is suit for applications where accurate clock reference is required |
ADC channel | 8 | 6 | CFG used as ADC6 by configuration, and ADC7 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 |
