DC Power Supply Module, AMS1117 Multiple Output 12/5/3.3V R2 (stepdown)

Description

• One input: DC 6V – 12V (input voltage must be higher than the output voltage to 1V or more.)
• Triple Output:
  • 3.3V (+ – 0.05v error)
  • 5.0V (+ – 0.05v error)
  • 12V (12V input directly to output)
• About AMS1117 – peak current ~1A, need heatsink if long time use on high current
• Specially designed two pin mounting holes, can be directly fixed to the tunnel plate to extend the experiment
• Using multiple input and output pin, easy to use and connect. One side 12V,5V,3.3V, one side Gound.
• PCB board size: 4.5cm * 4.5cm
• With power indicator light (red), has power on/off switch

R2 Version:

• Add 0R resistor to disconnect from AMS1117-5V
• Add selectable jumper from pin out to 3.3V directly or 5V.
• ON/OFF Switch only control ON/OFF of DC 5.5mm barrel jack, not pin VIN.
• To use our this kind of breakout board, remove 0R resisitor and set jumper to 3.3V output.
