content: Quote from: jeremy on October 27, 2014, 01:01:34 pminteresting... I've just finished an AM335x design - does that module have any components on the back? If I spent all that time laying out the power and decouplers, when a few caps around the edge would have done, I'll be sad.(Damn datasheets, always with the 'all these decouplers as close as possible to the pins'. I'd love to have the time to play, and see what's actually necessary for a safe design. Multilayer PCBs are now so cheap, maybe the time has come for a few variants, see how far I can push it (even if not for volume / customer designs).
