UNO PLUS, Improved UNO (Arduino-Compatible)

Description of product

UNO PLUS Features

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

UNO PLUS Vs UNO R3:

UNO PLUSUNO 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 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
