Accurate RTC Shield with Kapton Stencil
Accurate RTC Shield with Kapton Stencil
For the past couple of weeks I have been working with the DS3231 Maxim. This chip is a I2C based RTC with an integrated temperature compensated oscillator and crystal.This means despite changing temperature conditions, it will maintain a very accurate track of time. If you’re interested in the first rev of the PCB, let me know. I have a few available. They are functional, however, the prototyping area came bad.I have a set of new ones with a proper prototyping area, reset button, and power LED in process.

    I’m interested in your RTC shield using the DS3231. Do you have any available for testing? Any time estimate for firmware?

    • Hi Charlie, I just got in new PCBs but won’t be able to populate them until next weekend. Where are you located?
