Problem with 5V from power supply
Hi.
I have a connection problem, after so many errors thinking about updating and others, I have concluded that the fault is if I feed the MGerbil with the 5V of the power supply, if the food with the 5V of the usb there is no problem , it works perfectly but if I change the Jumper to be fed from the original power supply, it gives an error starting the work and stops, sometimes an open door error, sometimes an error on line 2, on line 21, on line 1 , etc.
Why, I have checked the voltage given by the original power supply and gives 5.05v, in theory it is correct.
Any ideas?
Probably it's a dirty 5V line (electrical noise like spikes etc.). You can add a filter cap of 100nF and a coil but using the USB 5v is fine too that's why we included the option.

Thank you. Where should I solder the resistor, near the board connector?
