Nice little board
I was skeptical about this board at first, but after I received it and checked it out I was quite pleased. Reasonably accurate and a quality looking board. I can remember when we could make products like this in the US but China is now so much further ahead of us in being able to deliver good products and a resonable price. Don't get me wrong I have received garbage form China as well.

Really nice to have this on my bench!
Works as described, and is an excellent tool for any digital bench.. Accuracy and stability are affected by temperature however this can be remedied by a thermally controlled enclosure..

Handy multiple output square wave generator
Super Low Frequency Square Wave Oscillator with 22 simultaneous outputs, from 1/(2k) Hz to 2kHzThe circuit I received is a newer version (1.4), having a red LED connected to the 1Hz output, indicating power on.A quartz crystal clock is divided by CD4060 and CD4040 ICs.The chips are rated for 3 to 18 volts input. 2.5 volts seems OK. :)

Does The Job
This board is really great at providing solid low frequency square wave signals needed for various projects. Good quality PC board. And they included a couple of headers too! Thanks!
