Alinan 5pcs DS3231 AT24C32 Clock Module IIC RTC Module High Precision Real Time Clock Module Memory Board Beats Replace DS1307 I2C RTC Board (with Battery)

Brand: Alinan

Features:

• 【Real Time Clock Chip】: DS3231 is a low-cost, extremely accurate I2C real-time clock (RTC), with an integrated temperature-compensated crystal oscillator (TCXO) and crystal. Two programmable time-of day alarms and a 1Hz output are provided. 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, to provide a reset output, and to automatically switch to the backup supply when necessary. In addition, RST pin is monitored as generating a μP reset
• 【Complete Clock Calendar】: RTC maintains seconds, minutes, hours, day, date, month, and year information. Less than 31 days of the month, the end date will be automatically adjusted, including corrections for leap year. The clock operates in either the 24 hours or band / AM / PM indication of the 12-hour format
• 【Parameter】: DS3231 AT24C32 Clock Module Real Time Clock Module Working voltage: 3.3V — 5.5V, Clock chip: high-precision clock chip DS3231M, Memory chips: AT24C32
• 【Satisfaction Guarantee】: If you have any questions during use, please feel free to contact us and we will reply you immediately
