Combo-Breakout mit DS3231 (Temperatur/Zeit) + 24C32 (Memory) Dieses praktische Breakout vereint zwei ICs auf einem Board: Dallas DS3231: Batteriegepufferte Echtzeituhr inkl. Alarm-Funktion und Thermometer Atmel 24C32: 32kBit EEprom Beide ICs werden über das I2C-Protokoll angesprochen und benötigen daher nur zwei IO-Pins (SCL, SDA). Die Libraries für den Arduino finden Sie natürlich ebenfalls ...

The datasheet for the DS3231 explains that this part is an "Extremely Accurate I²C-Integrated RTC/TCXO/Crystal". And, hey, it does exactly what it says on the tin! This Real Time Clock (RTC) is the most precise you can get in a small, low-power package. Most RTCs use an external 32kHz timing crystal that is used to keep time with low current draw. And that's all well and good, but those crystals

A Feather board without ambition is a Feather board without FeatherWings! This is the DS3231 Precision RTC FeatherWing: it adds an extremely accurate I2C-integrated Real Time Clock (RTC) with a Temperature Compensated Crystal Oscillator (TCXO)  to any Feather main board. This RTC is the most precise you can get in a small, low power package. Using our Feather Stacking Headers or Feather Female ...
