Product Description
The new version of 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. 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 a better reception with an even shorter antenna stick.
The new designed, fine tuned 60kHz antenna replaces the old 100mm long antenna, and ensures 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 0.4µV (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 a more flexible use. So is it 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 project, you can find many projects online, using 60kHz atomic clock receiver. From Arduino data logger to Nixon tube clocks. There are also libraries for Arduino IDE and other development sources online. We highly recommend to read the official Wikipedia article about WWVB (Fort Collins) time signal. * 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.Documentation is available on UNIVERSAL-SOLDER official website.
60kHz Atomic Clock Receiver Kit with Loop Stick Antenna.
The kit comes with the universal AM receiver board for 40-100kHz, a 60,003kHz crystal, a fine tuned 60kHz Antenna (60mm) with high Q-factor and high gain, and some male header pins. Antenna and crystal are not factory assembled.
CANADUINO Atomic Clock AM Receiver 40-100kHz.
The receiver module in SMD technology follows highest manufacturing standards on a high quality, gold plated circuit board, and comes with 4 status LEDs to show the current settings of AGC and PDN, the output signal, and the proper power supply voltage.
Optimized for solderless bread-board development.
The PCB comes with some male pin headers (not assembled) to use it for easy bread-board development.
More function than any other Atomic Clock AM Receiver.
The receiver board comes with an on-board voltage regulator, inputs for automatic gain control (AGC) and power down mode (PDN), 2 outputs (inverted and non-inverted), and 4 status LEDs to notify about the current setting and function. The LEDs can be disabled to save power for battery operated devices. Then the average current consumption is only about 0.1mA.

Reviewed in the United States on September 12, 2018
After soldering down a 5-pin breakaway header on the board, I put it down on a breadboard and wired it to an Arduino, and wrote a short test sketch to time the edges on the T pin, and saw the right kind of timings (800ms/200ms etc). This was done on a bench in the man cave/Faraday cage, so that's pretty impressive performance. As a secondary check, I turned on an LF receiver in the shack and verified the pulses lined up with what I heard on WWVB. Looking forward to writing a time decoder for this very slow and very accurate PWM'd bit stream.
Remember to pull down the P1 pin to turn on the receiver. It doesn't draw a lot of current (about 50 uA) when it's running, and draws near nothing (0.1uA) when you power it down (by pulling P1 up). The included documentation describes cycling this pin to retrigger the AGC logic to hasten signal acquisition time. You might therefore want to dedicate an Arduino output pin to controlling P1 rather than just grounding it. For my first test, I just grounded P1 and signal was acquired within seconds of power up.
Standard shipping is via the Canadian and US Postal system; it took about a week and a half to get here. Seller was really quick to reply on a shipping question. He didn't solicit a review from me, I'm just impressed with this inexpensive, sensitive receiver giving me WWVB on a pin.
Then I tried to make it work with an Arduino. The Universal solder points you to a couple outside developers on GitHub. One is useless since he never tested the code with a unit.
The other one seems OK, but he won't tell you what pins of the unit go where on the Arduino. Then he integrates it with a segment display that is no longer in production, and impossible to find.
Shouldn't the manufacturer develop working code for it?
Too bad,
Top reviews from other countries
Much more sensitive than the desk marathon clock I have that never synchronizes.
One needs other components if a full atomic radio clock is the end goal.
The advantages of a PLL is that it can cut through noise and deliver a clean output, albeit logic or simply ON/OFF. Their response to a synchronised signal is extremely fast and the rise and fall times are so brief as to be almost immeasurable i.e. nanoseconds. However, they do take a finite time to synchronise, sometimes minutes, but usually <30 secs or so, dependent upon signal strength.
This receiver, supplied by Universal Solder, has a sensitivity of 4 uV, which is quite respectable for a ferrite aerial. For those of you who reside at extreme distances from a transmitter, and who find reception poor to impossible, the signal to noise ratio may be improved by adding ferrite rods in a bundle (3 or so), surrounding the one already connected to this receiver. There have been some excellent reports about this receiver when operated at vast distances from their respective transmitters, especially from large countries like Canada and the U.S.
The receiver runs at a maximum of 5 volts and burns micro-watts of energy, it being CMOS based. The output pulses are DC, not r.f., and their amplitude will be within a few percent of the supply rail voltage. The minimum operating supply is 3.5V. at which it will perform quite well.
The aerial's ferrite-mounted coil is solid copper wire, not Litz wire, and is therefore quite brittle by comparison. Whilst it will tolerate a reasonable amount of flexing, great care needs to be taken when handling the 'heavy' ferrite rod and the minuscule micro-miniature p.c.b. when soldering etc. Namely, don't allow the ferrite aerial to dangle on the aerial wire, even accidentally. A second pair of hands will be useful when soldering the tiny lands associated with the additional connections.
Whilst we are always keen to 'give it a burn', you are strongly advised to mount the pcb and aerial as soon as you have made all the connections. You should browse for UniversalSolder.ca and select the device from the list of other units supplied by this company. The instructions are clear and easy to follow ... just three pages.
A point to note. Holding the receiver in your fingers will very likely introduce spurious or weakened r.f. signal response, as will the proximity of other loose wiring e.g. on a test rig. Leave the unit alone and be patient. Give it at least a minute to stabilise and produce pulses ... an oscilloscope isn't a must, but will prove quite reassuring.
For MSF Rugby users in the UK, the first 0-100mS is the Seconds' Pulse. From 100-200 is the code (one bit per second) and from 300-400mSecs is the 'B' code. A fully detailed information sheet may be found on Wikipedia MSF Rugby, if, like me, you are designing your own decoder using hardware.
All the work is done for you in this receiver, it producing nothing but seconds and coded output. In terms of performance, I don't think it will ever be bettered, as physics, in this case, have been mastered. It is a well- designed circuit, its small size enhancing performance.
P.S. You may find it difficult to remove the ferrite rod and circuit board from the 'test tube', as they are rammed in to prevent movement during transit, and pulling the board to extract the ferrite via its aerial wiring is not recommended! Saw off the end of the tube and push the ferrite rod out with a pencil ... better safe than sorry.

and it has proved very reliable. In that time I have only had to replace the Z80 processor,
which may have failed from overheating.
But I never had much success with the 60kHz receivers (two designs) and aerials (ferrite rod
and wire frame aerials). Aerials extremely directional and poor reception in daylight hours.
This Canaduino module has transformed the clock. It comes as a kit, but very little soldering
required. But you do need to be competent in soldering tiny parts (the crystal).
It was very well packed inside a small plastic box. I don't know whether the box was intended
to house the built-up unit, but that's what I did. With careful measurements and drilling I
mounted the ferrire rod with cable ties, the PCB with M2.5 screws, and two phono sockets.
One for power, the other for data.
It seems quite tolerant of direction, but I'm relatively close to the Anthorn transmitter
(about 135 km, 84 miles). It may be more critical at greater distances.
Highly recommended.
