Description of ⏰ ICQUANZX DS3231 AT24C32 Clock Module - Real Time Clock Module IIC RTC Module for Arduino (5PCS)

【Real Time Clock Chip】The DS3231RTC is used as a real time clock chip which keeps the time running even if the main power supply is off (with the help of a battery). 【Complete Clock Calendar】Functionality Including Seconds, Minutes, Hours, Day, Date, Month, and Year, with Leap-Year Compensation Up to Year 2100. 【Extremely Accurate】DS3231 16-pin memory chips - AT24C32 ,extremely accurate I2C real-time clock (RTC), with an integrated temperature-compensated crystal oscillator (TCXO) and crystal. 【Two programm】Provides programmable time-of day alarms and a calendar can be set to a square wave output. Address and data are transferred serially through an I2C bidirectional bus. 【Safe Enough】A precision temperature-compensated voltage reference and comparator circuit monitors the status of VCC to detect power failures, provide a reset output. In addition, RST pin is monitored as generating a μP reset.

Works as it should

These RTC and EEPROM modules work properly but contain a battery charging resistor (just above the SCL label). The package contains non-rechargeable CR2032 batteries. ML2032 is a rechargeable battery. The charging current provided is low and some people try to recharge these batteries but the battery data sheet states that they cannot be recharged. I removed the charging resistor and they work fine.

Pros
  • Full Clock Calendar
Cons
  • Upgradable

Simple clock/calendar for Arduino, Raspberry etc.

The DS3231 AT24C32 clock module worked perfectly and a CR2032 battery was supplied with each module. As other reviewers point out, the charging circuitry can damage the CR2032 battery. I removed the load resistor to disable this circuit. The module works normally and keeps time when the device is off. 1 star deducted because the seller should have identified a known issue with the charger. See the following forum thread for a six year discussion: forum.arduino.cc…

Pros
  • Computers and accessories
Cons
  • Big and chunky
