Description

經過幾個月的“斷貨”後,DS1307 RTC模塊經歷了全面升級。它帶有Gravity I2C接口,並且其尺寸也減小了以適合小型化應用。 Gravity I2C DS1307 RTC模塊是一個易於使用的實時時鐘模塊。可用其製作時鐘,數據記錄器等,它的價格便宜且容易負擔。新版本的DS1307 RTC模塊採用高精度晶體振盪器,可大大減少時間誤差。測試顯示,時間誤差在24小時內僅為1秒左右(機械表的平均時間誤差約為20秒)。該模塊由單電池CR1220供電(使用壽命3至5年)。它體積較小,並保留EEPROM 4KB ROM來記錄與鬧鐘和事件有關的信息。此外,您可以通過電阻調整來設置I2C地址。 Gravity DS1307 RTC模塊使用Gravity I2C接口,您可以將其直接插入DFRobot Gravity IO擴展擋板。與DFRobot開發的Arduino DS1307庫配合使用,可以輕鬆實現設置時間和時間顯示等功能。它可以廣泛地用於DA(數據採集)中。 

注意:根據最新的《航空運輸法規》,電池CR1220將不再隨模塊一起提供。請自 

行購買。
