4duino Uno

This board is fully software, hardware and mechanically compatible with an Arduino Uno. But we have taken the design several steps further and added full access to all 8 of the Analog inputs via holes on the board

This is a depopulated version of the 4duino Uno Pro, so you can always added the extra components and headers to bring it up to the same specification.



  • Processor: ATMega328P-AU
  • Speed: 16MHz
  • Digital I/O pins: 14 (5 with PWM)
  • Analog I/O pins: 8 (6 can be digital I/O)
