What's The Differences

  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

Connecting With Waveshare Shields

Connecting With Motor Control Shield And IO Expansion Shield

Connecting With Sorts Of Sensors
