| + | Should have a 3.3v fixed output as well as the 5v. Easy enough to handle. 1A should be good for most purposes on the fixed supplies. Elektor ran a switching PSU module in April that I made some tweeks on and currently as waiting on boards. Galvanically isolating the adjustible supplies is a potential issue. As soon as you hook a meter panel up, the two supplies are tied together. Hack around it by using two MCUs for A/D and transmitting to a third one via optoisolators?--pstemari | ||
