Wiring: Power Adapter to Board

From the previous step, Wiring: Power Adapter to Coinslot, you’ve already connected a Red Wire to DC Jack’s “+” and a Black wire to DC Jack’s “-’. 

You’ll need another wires to splice it to the Red and Black Wire (connecting the Female DC Power Jack Adapter and Coinslot). 

1. Using another wire (preferably  red to easily identify), splice one end of this wire  to the “Red Wire”  that is connected from Female DC Power Jack Adapter’s “Positive (+) ”.
2. And using another wire (preferably black to easily identify), splice one end of this wire to the “Black Wire” that is connected from the Female DC Power Jack Adapter’s “Negative (-). 
3. Connect another end of the spliced “red wire” to Buck Converter’s “Positive (+)”.
4. Connect another end of the spliced “black wire” to Buck Converter’s “Negative (-)”.
5. Connect the power cord from buck converter’s USB Port to the board’s micro-usb power input. 

Your board  should be ready to power up. But let’s proceed to “Wiring: Coinslot - Board'' first.
