  "summary_zh": "這款時鐘模組採用Maxim DS3231核心，為極精確的RTC芯片，它管理所有計時功能，並具有簡便的I2C接口，可以輕鬆地與Arduino, Raspberry Pi連接。\nMaxim DS3231芯片保留秒，分鐘，小時，日期，日期，月份和年份的信息。對於少於31天的月份，將自動調整月末的日期，包括leap年的更正（有效期至2100年）。\n帶有AM / PM指示器的時鐘以24小時或12小時格式運行。它還提供了兩個可編程的時間鬧鐘。\n還帶有一個很酷的功能是帶有SQW引腳，它可以依1Hz，4kHz，8kHz或32kHz的頻率輸出漂亮的方波，並且可以通過編程方式進行處理。",
