mamu, maybe it's my poor english, but I don't understand how you connected two boards.
1. Did you use a single pot (contacts on both boards connected together) or doubled one, each resistor to each board?
2. According to voltages, you connected both to one power supply, but what about outputs? You just connected them in parallel? Plus to plus and minus to minus? Without shottky diodes? If so, is it documented somewhere? I mean, every board is a little different, so output voltages are also different. Is it possible to use them simply in parallel? Or you did a trick?
P.S. for me even 10-12 watts is too much, but my friend wants a power supply with approx 20 watts, but he is not so powerful in schematics![]()
It's not documented how to do the dual boards. I watched Brandon's interview on VPLive and saw how he wired a dual setup then did mine the same. It is easy and simple to do and is a parallel setup - matching one pin on one board with the same pin on the other board. One board sits directly on top of the other board lined up pin-to-pin. I just created a solder bridge from the pin of one board to the same corresponding pin of the other board.
There's no doubling on parts. The same one trimmer that you use on the single board is also used for the dual setup. Once you've got the dual boards wired pin-to-pin it acts like one board, not two.
I just got the dual board in a mod and completed. Am vaping with it now at 16 Watts. nom nom nom
Will post pics in a bit.
