Re: Hot, 25pe40vp chip (U2)

Hi, I use a external voltage regulator for the relay module.
the changing voltage are never above 14.2V (AMG Battery) I have a solar regulator that regulate the changing.

I will change the setup to use 1K resistor on all pins like you suggested.

Re: Hot, 25pe40vp chip (U2)

Hi petergebruers, If I understand you correctly, I should for safety reason connecting all pins, except 7-18,5v,GND and 3v3 to Ground with a 1K resistor? I am not connecting the ULN2003 directly to the coils (this module have a seperate power supply): https://www.dropbox.com/s/j9s5nh3rihshvjl/Fil%20...

To summon the connections, i had 6 inputs where I use ground for signal I had 4 relay outputs, and 6 led output...

Hot, 25pe40vp chip (U2)

Have anyone experience the Flash chip 25pe40vp to become extremely hot?

after some seconds the chip gets burning hot and the z-uno stops working.
