What board supports 2 external inputs to internal counters


I have used the Mega2560 in the past, and been happy with that, but I could really use a board with two external inputs to internal counters.

The Mega has two, but one is used to internal timing purposes (e.g. delays).

I have looked at the other boards, but I am missing information about how many counters that are accessable via external pins.

This is what I need, any suggestions for a board that would support that:
10 Analog inputs
16 Digital outputs (6 of them with pwm)
2 external inputs to internal counters.

What do you mean by external inputs to counters? External clock? input capture?

Mega has:
– Two 8-bit Timer/Counters with Separate Prescaler and Compare Mode
– Four 16-bit Timer/Counter with Separate Prescaler, Compare- and Capture Mode

Look for pins with Tx in their name - T0 to T5.
On the Mega schematic, not all of these are brought out to user accessible pins. I offer a couple of board form factors where ALL IO pins are made accessible, such as this one:

and this one
which came about from this forum discussion

We’ve only assembled a few so far, our fine pitch soldering technique is not the best yet so solder cleanup between pins is a bit laborious.
