Re: Board won’t power up.

Check on the uBitx board if you get the 12V power. Start first just below the power jack P1.
Sometimes these wires are crimped well and may not be making contact.
It is almost impossible to see uA unless something drastic wrong with P1 or your measurement! This has happened before.

I think my microBitx main board may be defective. When powered up (without the raduino attached), according to the wiring instructions, it only draws 60-80 micro amps, rather than 90-110 mA the instructions specify. I have checked twice that the sacrificial diode is installed correctly.
