Doubtful. If you notice, the counting module has a maximum count rate on the
order of 7 counts/sec. It seems they put in a bit of debouncing hardware. I
was quite disappointed by this, as my application needed closer to 30
counts/sec. But I hacked around that by adding enough circuitry to add another
digit (LED) to the counter, useful until I could mail order a counter more
suited for the speed that I needed.
