The pcb with LM317 and LM337 regulators
Click on the picture to get a larger view.
This pcb is pretty simple to solder. You just have to place the parts in their right locations and it may be practical to start with small parts first. Check carefully which parts you will use for each configuration. If you'll prefer SMD caps you could use 0805 XR7 types. C7 and C8 isn't always necessary. See the datasheet for more info.
You could wait with mounting the DRV134 until you have tested the regulators.

Check carefully which parts you will use for each configuration. The LED's could be tricky to polarize right but the long leg is plus. If you'll prefer SMD caps you could use 0805 XR7 types.
