A 60kHz WWVB Atomic Clock Receiver is a device that receives the time signals transmitted by the National Institute of Standards and Technology’s (NIST) radio station WWVB located in Fort Collins, Colorado, USA. The receiver decodes the time signals to synchronize the time and date on atomic clocks, which are accurate to within a few microseconds. WWVB broadcasts time signals on a frequency of 60kHz and provides a continuous, reliable source of coordinated Universal Time (UTC) for the US and other regions of the world.
We designed this product around the awesome receiver chip from Micro Analog Systems (Finland). This module is in particular designed for use with microcontrollers in an operating voltage range of 2 to 15V, and standard logic levels 3.3V / 5V.
The kit includes a high-quality, fine-tuned 60kHz antenna with a Q-factor of over 100.
The WWVB Atomic Clock AM Receiver module can also receive any other 60kHz atomic clock AM signal, like:
– JJY60 (Japan)
– MSF (England)
The advantages over other modules from other manufacturers:
– wide operating voltage range 2* to 15V
– 60 mm tuned high-gain, high-Q antenna
– current consumption <100µA (LEDs off)
– super high sensitivity of 0.4V (RMS)
– power down control pin
– fast start-up
– AGC control on/off
The kit needs soldering. Crystal, antenna, and pin header are not factory assembled.

If you don’t want to develop your own code, you can find many projects online, using our receiver kit, like for example Bruce Hall’s perfectly documented WWVB Clock with TFT colour display:

We highly recommend reading the official Wikipedia article about WWVB (Fort Collins) time signal to better understand how these clocks work.

Please find the Atomic Clock Radio Signal Map on NIST website to learn about the signal coverage.
We decided not to publish a new manual for the new module since the differences from the predecessor are only minimal.
* The module will work as expected with a voltage of as low as 2V. But the LEDs might not work as expected. We recommend a minimum voltage of 3V.
