On the oscillator plug (p3) 12 volts is fed into pin 15 (orange wire). From there it goes to the input side of the 5 Volt regulator. The other connections are ground and the frequency out to the (red and brown) main board. The black is ground.

Hi. Could you clarify this? On the wire up diagram, the Raduino is clearly labelled as getting 12 volts and a ground connection. I am guessing that 12 volts can be connected back to the 12 volt power jack. Or is this incorrect? As it is, the diagram and the wire up instructions do not match, and your comment has created even more confusion for me.

I let smoke out of the display board on my BitX by sending 12 volt power to the WRONG orange wire.? Very important to NOT put 12 volts on one of the pins of the processor chip, it goes POOF!

Seven dollars later on Amazon a new Arduino Nano is installed and I¡¯m having a lot of fun with this little rig
