The Elegoo kit came with a power supply module, shown below. This board simply plugs into a standard bread board, and supplies power to the rails. This is convenient if you want to be able to supply 5V or 3.3V external to the Arduino power (i.e. driving motors).
Ensure that when installing you note the orientation so (+) is in the positive line and (-) is negative.
- Input is 6-9V
- Output is either 3.3 or 5V (based on jumpers)
- Max Output Current: 700mA
