Description: The PCF8523 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 . If you need a DS1307 for compatibility reasons, check out our DS1307 RTC breakout. 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. Equipped with PCF8523 RTC - it can run from 3.3V or 5V power & logic. 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. Package Included: 1* PCF8523 RTC Real Time Clock Breakout Board 1* Pin Header. |

Energy saving The ESP32 is a chip designed with TSMC technology for extremely low power consumption (ultra-low power management), allowing for the best power and performance with its high efficiency. As the quiescent current of the ESP32 chip is less than 5 μA it is particularly suitable for use with batteries or rechargeable batteries Compatible It has a similar pin layout to the conventional D1 Mini ESP8266-12F and is therefore pin-compatible with most accessories for it.
