Description
This is a battery-backed real-time clock that is perfect for use with microcontrollers. It is compatible with an Arduino or a Raspberry Pi, and includes a PCB and header. It will keep time for 5 years or more, and is simple to use.
This is a great battery-backed real time clock (RTC) that allows your microcontroller project to keep track of time even if it is reprogrammed, or if the power is lost. Perfect for datalogging, clock-building, time stamping, timers and alarms, etc. The DS1307 is the most popular RTC - but it requires 5V power to work (although we've used it with 5V power and 3.3V logic successfully) Works great with an Arduino using our RTC library or with a Raspberry Pi (or similar single board linux computer)
PCB & header are included
Plugs into any breadboard, or you can use wires
Two mounting holes
Will keep time for 5 years or more Note: This product does not come with a CR1220 coin cell battery. We recommend you purchase a coin cell battery to use with this product. The DS1307 is simple and inexpensive but not a high precision device. It may lose or gain up to 2 seconds a day. For a high-precision, temperature compensated alternative, please check out the DS3231 precision RTC
