Waveshare Arduino Uno Plus Kit

Improved version of the classic Arduino Uno Board, with all the layout mistakes of the standard Uno removed but completely compatible with the original units. Features an AVR ATmega328P microcontroller

Uno Plus Advantages

  • Operating voltage 5V/3.3V not just 5V
    Dual voltage level to support more shields
  • Lateral Reset Switch not vertical
    Lateral button is easier to use when connecting with shield
  • Has Bootloader switch
    The board can be configured to run program immediately when power-up by the switch
  • Micro USB USB connector not USB Type B
    Micro connector is more commonly used, and shields won't be blocked anymore while connecting
  • Low profile DC jack not normal height
    Shields won't be blocked when connected
  • Power output header
  • Provides 5V/3.3V power output OR common-grounding with other boards
  • 800mA 3.3V power output not 150mA Max
    UNO PLUS features higher driving capability
  • Crystal oscillator not ceramic resonator
    Crystal oscillator gives accurate clock reference
  • 8 ADC channels not 6
    CFG used as ADC6 by configuration, and ADC7 from the Reserved PIN
  • Supports connecting prototype breadboard
    Solder pads are provided for connecting prototype breadboard
  • USB driver compatible with all OS
    Driver never fails to install thanks to the onboard FT232
  • Firmware fixing supported
    Firmware can be fixed by using the onboard FT232, no extra programmer is needed

Arduino Uno Plus Main Features

Waveshare Arduino Uno Layout
  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
  6. compatible with standard Arduino interface with two additional analog inputs A6 (config the CFG), A7
  7. solder pads provided, supports prototype breadboard
  8. ICSP interface
  9. MICRO USB connector : for uploading program OR serial port debugging
  10. 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
  11. FT232 pins : for burning Bootloader into the microcontroller
  12. DC input : 7V ~ 12V
  13. Reset button
  14. Power indicator
  15. Serial port Rx/Tx indicator
  16. User LED
  17. Power configuration switch : for configuring the operating voltage
  18. 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
