Kamami is the official distributor of Waveshare displays, accessories and modules.

Description

UNO PLUS is a development board compatible with the Arduino UNO R3, an improved & enhanced alternative solution for Arduino UNO R3.

Advantages:

Waveshare
UNO PLUS		Arduino
UNO 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 UNO 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

  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
