What's The Differences


R3 PLUSOFFICIAL R3REMARKS
Operating voltage5V/3.3V5VDual voltage level to support more shields
ResetLateralVerticalLateral button is easier to use when connecting with shield
Bootloader switchYesNoneThe board can be configured to run program immediately when power-up by the switch
USB connectorMicro USBUSB Type BMicro connector is more commonly used, and shields won't be blocked anymore while connecting
DC jackLow profileNormal heightShields won't be blocked anymore while connecting
Power output headerYesNoneProviding 5V/3.3V power output OR common-grounding with other boards
3.3V power output800mA Max150mA MaxR3 PLUS features higher driving capability
OscillatorCrystal oscillatorCeramic resonatorCrystal oscillator is suit for applications where accurate clock reference is required
ADC channel86CFG used as ADC6 by configuration, and ADC7 from the Reserved PIN
Connecting with
prototype breadboard
SupportedNot supportedSolder pads is provided for DIY interfaces to connecting with prototype breadboard
USB driverCompatible with all main systemsDoesn't compatible with WIN7/WIN8 Express EditionDriver will never failed to install thanks to the onboard FT232
Firmware fixingSupportedNot supportedFirmware can be fixed by using the onboard FT232, no extra programmer is needed

What's On Board

  1. ATMEGA328P-AU
  2. AMS1117-3.3
    3.3V voltage regulator
  3. NCP1117ST50T3G
    5V voltage regulator
  4. FT232RL
    USB to UART convertor
  5. Arduino interface
    • compatible with standard Arduino interface with two additional analog inputs A6 (config the CFG), A7
    • solder pads provided, supports prototype breadboard
  6. ICSP interface
  7. MICRO USB connector
    for uploading program OR serial port debugging
  8. Power output header
    3.3V OR 5V, voltage level configured by the onboard power configuration switch, used as power output OR common-grounding with other boards

 

  1. FT232 pins
    for burning Bootloader into the microcontroller
  2. DC input
    7V ~ 12V
  3. Reset button
  4. Power indicator
  5. Serial port Rx/Tx indicator
  6. User LED
  7. 500mA fast auto-recovery fuse
  8. Power configuration
    for configuring the operating voltage
  9. Bootloader selection switch
    • turn ON: the board will reset when power-up OR other USB devices were detected connecting to the PC
    • turn OFF: the onboard program runs immediately when power-up, and the board will not reset when other USB devices were detected connecting to the PC
