No LED. Schematic on website suggested it has more features than physically present on the board. The freqency range did not adjust below a few kilohertz, as provided. It was more like 2-5khz and not 5-2khz, as stated.

Simplemente funciona. Los potenciómetros multivuelta hacen que sea muy fácil afinar la frecuencia de salida.

Hey I'm trying to power this with a 9-volt battery which should work according to a little information I can find. But it gets very hot and the frequency is completely unstable. Is there something I am missing? Is there too much amperage coming out of of 9 volt battery? I've seen lots of any 555 homebrewed frequency circuits that just used a straight 9 volt battery. Not enough information on your site to get this to work right.
