After our recent RTC part finder post, Adafruit friend Kevin Townsend wrote in to tell us about a accurate RTC that he’s been using, the PCF2129. Its half the cost of the DS3231 – but only runs up to 4.2V logic instead of 5V. Still, for all you using 3.3V logic or lipo’s its a great deal and a good replacement for the DS3231 when you need high accuracy temperature compensation timekeeping!
