Sobre este producto
- 【Parameter】: Working voltage: 3.3V-5.5V; Clock chip: high-precision clock chip DS3231M; Memory chips: AT24C32(Storage capacity 32K);
- 【Real Time Clock Chip】: DS3231 is a low-cost, extremely accurate I2C real-time clock, with an integrated temperature-compensated crystal oscillator 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.
- 【IIC bus interface】Transmission speed 400KHz (when the operating voltage is 5V); other IIC devices can be cascaded, the 24C32 address can be modified by short-circuiting A0/A1/A2, the default address is 0x57.
- 【Complete Clock Calendar】: Real time clock 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.
- 【Battery Not included】You need to prepare CR2032 or LIR2032 battery by yourself.not included in the package.
