Frequently asked questions
Can I power an Arduino Uno from it?
Yes, feed the 5 V output into the board's 5V pin with the grounds shared. The 1 A rating covers typical boards and sensors, but high-current loads such as multiple servos need a higher-rated supply.
Does it work with a 12 V car battery?
Yes. A 12 V battery is inside the 9 to 18 V input range. Add a fuse on the input and make sure the battery is charged, since the input voltage falls as the battery discharges.
