eumir Posted October 25, 2005 Report Posted October 25, 2005 I finished my Sid and Core modules and voltages were Ok. Then I interconnected them and, when I power them both, Sid voltage drops to 2.4  If I only power the Sid module, even with both interconnected, the voltage´s fine, but as soon as I power the Core module, it drops again. ??? (no IC´s)  Damn, I was so close...
raphael Posted October 25, 2005 Report Posted October 25, 2005 What PSU are you using?Which Voltage is dropping: 12/9V or 5V?When you connect 12/9V and 5V to the SID only, what do you get?
eumir Posted October 25, 2005 Author Report Posted October 25, 2005 I´m using a 15v-1.0A wallwart. Sid voltage drops from 12v to 4.5v, and the 5v drops to 3.8 now. ???

What do you mean with "now" ??? here is the difference to your first setup?Could you give any more details? Like at which pins you connect what and so on....In general: Recheck your PCB for bad soldering or solder joints again and again and....
eumir Posted October 26, 2005 Author Report Posted October 26, 2005 The problem´s solved now ;D It was the wallwart. Cheap crap!
