#Adafruit PiRTC
|
|
|
|
This is a great battery-backed real time clock (RTC) that allows your Raspberry Pi project to
|
|
keep track of time if the power is lost. Perfect for data-logging, clock-building, time-stamping,
|
|
timers and alarms, etc. Equipped with PCF8523 RTC, it works great with the Raspberry Pi and has native
|
|
kernel support.
|
|
|
|
This RTC will keep the time for about 5 years. The PCF8523 is simple and inexpensive but not a high
|
|
precision device. It may lose or gain a second or two per day. |
