Larduino Uno is a superior microcontroller board, comparable to the Arduino Uno R3. Larduino UNO is fully compatible with Arduino UNO R3 and Arduino IDE open-source development environment.


  • features:
  • Power supply IC , redesigned to change from AMS1117 to LM7085.
  • Change from USB type B jack to micro-USB jack.
  • Isolated power supply between USB port and input DC jack. 
  • 1 channel DAC (digital-to-analog converter).
  • extra pin headers pads.
