A common and insanely versatile timer/oscillator from TI - blink an LED, generate tones, triggers and thousands of other uses.

Accurate timekeeping, even during power outages.

Periodically cycles power to your project, greatly extending battery life.

With some development boards, low power usage is an afterthought. Especially when price and usability is the main selling point. So what should you do when it's...

This precise RTC adopts DS3231M chip, which integrates MEMS resonator and temperature compensator. Compared to quartz crystal clock, the real-time clock reduces...

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 data-logging, clock-building, time stamping, timers, and alarms, etc. Equipped with PCF8523 RTC - it can run from 3.3V or 5V power & logic!

We're glad to introduce a new member in Gravity family: Gravity I2C SD2405 RTC module. This is an extremely accurate I2C real-time clock (RTC) with crystal compensation...

This is a common 555 timer/oscillator from TI. A classic for all of those first year circuits projects where you need to blink an LED, generate tone, and thousands...

The real-time clock RTC breakout module employs the SD3031 chip with an integrated crystal oscillator and temperature compensator and a built-in 70-byte...

Never hunt around for another crystal again, with the Si5351A clock generator breakout from Adafruit! This chip has a precision 25MHz crystal reference and internal...

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...

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...

Good stability and far more accurate than MCU internal oscillators.

With some development boards, low power usage is an afterthought. Especially when price and usability are the main selling points. So what should you do when it's...

his module adds a real, hardware clock to your Raspberry Pi. This means that having an accurate system clock is no longer dependent on having an internet connection - perfect for Pis that are remote or have only intermittent access to the internet, but still need to log data or schedule tasks.

PDIP-8 Package.

Sometimes we want our projects on, but sometimes we want to turn them off for a while to save power. The SparkFun Nano Power Timer will run while only consuming...
