Mini Buck placement on Pixleblaze

Hi, can somebody tell me where to solder the mini buck converter on the pixelblaze controller? Thank you.

Do you mean the buck converter sold in the electromagnetic store? And which PB? The full one or pico?

Yes, the mini buck converter sold by Electromage and the full Pixelblaze. I’m very new to this world and thank you for asking for clarification.

The mini buck is connected before pixelblaze. It doesn’t mount to the board. GND/negative is connected from your 12v power to the mini buck and PB. The input of the mini buck goes to positive 12v. The output of the mini buck goes to PB.

Thank you for very much for the clarification! That was the conclusion I reached after studying your No-Soldering LED Wiring Adapters X12. Thanks for the affirmation!
