[time-nuts] TADD-2 Mini Sine or Square signal input?

[John Ackermann N8UR]

Hello Edgardo --

The T2-Mini uses a wide-range input circuit based on one that Wenzel published with some modifications.  It works with a square wave input (I've done some limited testing) but I can't verify whether the input amplitude range will extend as far on either the low or the high side.

If you want to drive with a true TTL signal, you could bypass the input circuit entirely and feed directly into the PIC, though that would require some soldering.
