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 headerYesNone

Providing 5V/3.3V power output OR common-grounding with other boards

3.3V power output800mA Max150mA MaxUNO 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 breadboardSupportedNot 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 the UNO PLUS

UNO-PLUS on board resource

  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
  9. FT232 pins : for burning Bootloader into the microcontroller
  10. DC input : 7V ~ 12V
  11. Reset button
  12. Power indicator
  13. Serial port Rx/Tx indicator
  14. User LED
  15. Power configuration switch : for configuring the operating voltage
  16. 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
