Pico-RTC-Hat

Pico RTC HAT

Pico RTC HAT is a Real-Time clock expansion module with the powerful IC DS3231, backup battery holder, operating voltage 3.3 V, and Fast (400kHz) I2C Interface that measures the time which aligns the time of the device with the “Real-Time”. It is developed with the standard Raspberry Pi Pico header that supports the Raspberry Pi Pico series to enhance its efficiency at a low cost.
