ATMEGA328P Microcontroller Development Board, Arduino-Compatible

R3 PLUS MCU Development Board

Based On ATMEGA328P-AU

Compatible with the Arduino official R3 board


What's The Differences

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

    • 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
