Thanks for the suggestions. My client already has Peltier devices for deployments that need it. But saving power is a major issue so getting a board that is rated at 85C and not needing to cool it is much better than using electricity on Peltier devices. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/ _______________________________________________ luv-main mailing list [email protected] http://lists.luv.asn.au/listinfo/luv-main
