Hello Seb,

But every time when you need 3.3V on a shield you also want to power your main board with 3.3V so that you don’t have to deal with voltage level adjustments, well than it is the easiest way. In my opinion is 3.3V on the spare pin of the power connector AND 5V selectable between 3.3V and 5V the most flexible option (but off course also the most impact on the pcb) > > OK, I'll try to find one of these. > I've ordered more copper clad boards & more stuff on eBay, I hope to receive > them this week so I can build this upcoming board next WE. Lets hope the next one will be the final one for Jaluino Medium homebrew > > Cheers, > Seb Greetz Richard --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "jallib" group.
