Review on ⏰ Accurate Time Tracking with Adafruit DS3231 Precision RTC Breakout [ADA3013] by David Plunkett

Revainrating 5 out of 5

Extremely accurate and easy to use

I've used eight of these in various clock based Arduino and ESP8266 projects. They are extremely accurate. I had them in clocks that worked for 6 months without wasting time. The Arduino library for DS3231 is very simple and easy to hook up. I made a clock that checks internet time weekly and the settings were 0 seconds.

Pros
  • Happy so far
Cons
  • I'll write back later
