Re: Board won’t power up.



Check the voltages with your -ve probe on the mother board. In case there is a ground fault in P1 or wire!

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.

Any ideas how to proceed?
