The RTC chip has been moved to the bottom of the ChronoDot. It does not interfere with use on a solderless breadboard since the chip height is about the same as the plastic spacers on the headers. The chip has been upgraded to the DS3231SN, which is rated for the industrial -40C to +85C temperature range instead of the old ChronoDot's 0C to 70C temperature range. Please note that use at the higher or lower temperatures can reduce accuracy to +/- 3.5ppm instead of +/- 2.0ppm.
An error was made on the bottom silkscreen layer. Embarrassing since it's our logo, but ultimately irrelevant to the device functionality.
