The new version of the UNIVERSAL-SOLDER / CANADUINO atomic clock receiver module is the most advanced and best-equipped AM Atomic Clock Receiver module available today..
We designed this product around the awesome receiver chip from Micro Analog Systems (Finland), just like the old module was. It means, this module is in particular designed for the use with microcontrollers in an operating voltage range of 2 to 15V, and standard logic levels 3.3 / 5V.
This is new:
– We added an ultra-quiet LDO voltage regulator, to offer a wide supply voltage range of up to 15V.
– We added 4 LEDs to show the status of power, AGC, power-down mode, and output.
– We added drivers for the output signal, and an inverted output, both capable of driving up to 15mA.
– We modified the antenna design for better reception with an even shorter antenna stick.
The new designed, fine-tuned 60kHz antenna replaces the old 100mm long antenna, and guarantees even better reception than the old model.
This module can be used to receive the atomic clock signal transmitted by:
– WWVB (US/Canada)
– JJY60 (Japan)
– MSF (England).
The advantages compared to other modules:
– 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
This kit needs some soldering. Crystal, antenna, and pin header are not assembled for more flexible use. That way it is possible to use a different crystal and different antenna, for example for a 40kHz setup for Japan, or a DCF77 setup for Europe.
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.

Documentation for the old model is available here.
* 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.
The module looks dead and no LED turns on? You missed looking at the schematic and/or reading the datasheet, top of page 2, description of the module’s connections.
