If you are unable to program your Produino controller it is possible that it is stuck in DFU mode. In this instance we recommend trying the following procedure;


  • Connect Produino to the PC and turn it on. (Preferably a Windows PC)
  • Open KEIRO.
  • Select Produino.
  • Go to settings (gear icon top left corner).
  • Scroll down to “Recovery (from DFU Mode)” and click on its button.
  • Follow the instructions on the screen.
    • Note that this might take some time.
    • This will reset the Produino with the latest firmware.


If this does not resolve your problem please raise a support ticket.
