You can power it with a regulator chip but the slightly harder part is getting the 3V serial port level shifted to either 5V or RS232 and the same for the PPS. You can do it with a few transistors but maybe it introduces error or noise if you are not carful. I've used the 3.3 volt Oncore and really the hardest part is the new smaller connectors that you have to find. One good thing about the Oncore series is the quality of the documentation. All those commands are explained. -- Chris Albertson Redondo Beach, California _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
