Power Options

⚠Hardware reset button(only present on some Arduinos) *Not attached

  • USB port, connect to a PC or a mobile phone charger (5V, 2A)
  • The barrel plug does not have a function anymore, DO NOT USE!!!

⚠The micro USB connector of the arduino used in Cartridge Reader is very fragile and easily broken, so we strongly recommend using a magnetic cable.

*The warranty applies to any magnetic cable.
It does not matter which market you purchase in your country.
We hope will reduce the number of sad accidents.
