Geekstory 2PCS DS3231 AT24C32 IIC RTC Clock Module High Precision Real Time Clock Module Sensor for Arduino DIY
Description
DS3231 Real Time Clock Module DS3231 is a low-cost, high- precision I2C real-time clock (RTC), with an integrated temperature- compensated crystal oscillator (TCXO) and crystal. The device includes a battery input terminal, which can maintain timing when the main power supply is disconnected. Wiring instructions For Arduino U/N/O R/3 Board SCL → A5 SDA → A4 VCC → 5V GND → GND Battery Type: CR2032 or LIR2032 Battery is not included Description Parameter Clock Accuracy :0-40 ° range, the accuracy 2ppm, the error was about 1 minute With two calendar alarm clock Programmable square-wave output Real time clock generator seconds, minutes, hours, day, date, month and year timing and provide valid until the year 2100 leap year compensation Chip temperature sensor comes with an accuracy of ± 3 ° Can be cascaded with other IIC device, 24C32 addresses can be shorted A0/A1/A2 modify default address is 0x57 Size: 38mm (L) 22mm (W) 14mm (H) Weight: 8g Operating voltage: 3.3-5.5 V Clock chip: high-precision clock chip DS3231 Memory chips: AT24C32 (storage capacity 32K) IIC bus interface, the maximum transmission speed of 400KHz (working voltage of 5V) Read more
