ggrieve This was my first thought, until I figured out how to adjust the current and voltage potentiometers. I'm not sure that a 2.2 volt difference between input and output is enough for correct operation. Have you tried with a higher input voltage?

ggrieve If the Red LED is lit, this may mean that your output is shorted. How have you mounted the board? You CANNOT mount the board to a metal surface, as this will short the input to the output and may damage the board. Wind the current potentiometer fully anticlockwise to start, place a load across the output, monitor the output current and voltage, and increase the current potentiometer until the Red LED lights. Adjust current and voltage potentiometers to obtain your required output. Starting with a high-current load and the current potentiometer fully clockwise may damage the unit.

KJAlcro It's the left one. I'm not sure about the led. I have to check my one to see
