Arnak Posted March 24, 2008 Report Share Posted March 24, 2008 Hi,Could someone advise me on the voltage range to be expected unde load on the core module please?I have checked some of the core module test points and get 3.41v under operating conditions.I do have 5v at the DIN module connections.Is this within an acceptable range?Perhaps I should mention I am using a 1500ma supply at 9v.

stryd_one Posted March 25, 2008 Report Share Posted March 25, 2008 Sorry Arnak can you be more descriptive? 3.41V would be too low at most points (the correct voltages are listed on ucapps.de) but could be normal at some of them. Quote Link to comment Share on other sites More sharing options...
Arnak Posted March 26, 2008 Author Report Share Posted March 26, 2008 Hi Stryd_one,Thanks for that, I'll check out ucapps again, it's probably a bad joint on the core board.Arnak Quote Link to comment Share on other sites More sharing options...
bill Posted March 26, 2008 Report Share Posted March 26, 2008 I am using a 1500ma supply at 9v. Wow!It's off topic but :Take care and dont short circuit anything, 1500mA is pretty much current ;)(200mA should be far enough for most mb purpose, even with a backlighted lcd screen) Quote Link to comment Share on other sites More sharing options...
Arnak Posted March 27, 2008 Author Report Share Posted March 27, 2008 Hi Bill,Yes, good point,I'll be careful.The large supply is for the further code modules (3) and DIN and DOUT boards that will need to be driven, about 18 in all!!Arnak Quote Link to comment Share on other sites More sharing options...
