DFRobot Breadboard Power Supply

Hi - I plugged 12VDC into this breadboard power supply. On one rail I get 3.3 v as expected. On the other rail I get 12v. I was expecting 5v. Are jumpers required to be inserted onto the board to get 5 v?

Hi @RobotDave and welcome to our forum.

I see with jumpers that you can choose between 3.3V and 5V but not 12V.

What happens when you power it via USB and not from 12V power jack?
