Arduino Power Supply - 12V 2A - High Voltage (Universal) [discontinued] _ARD_COMPAT The only downside is theyLooking for an Arduino Power Supply? You're in the right place! The Arduino UNO is very flexible when it comes to power requirements, and is able to operate via the DC Barrel Jack on a supply of 6 to 20V. However, if the board is supplied with less than 7V, the units performance could become unstable, and the 5V I O pin may end up supplying less than 5V, which could cause additional circuitry to function incorrectly. Vice versa, using an over voltage
