Re: Clearpath Servo Motors and Step/Dir/Enable Pin Avaiability

Hi!

is it possible to use a PanelDue on CONN_SDCARD

and simulaneously use the two STEP/DIR channels on CONN_LCD ?

[djstree]

Forgive the quick sketch ... Thinking about a breakout board like so.

Those NL37WZ16 buffers have very nice output drive characteristics. Unfortunately they specify a minimum Vih of 0.7V * Vcc, which at VCC=5 is 3.5V. That's more than the 3.3V nominal (and possibly as low as 3.2V) provided on the expansion board connector.

@dc42 good spot, thanks.. I'll find another part.

If you feed +5V and IN- to the Clearpath input instead of IN+ and ground, then you could perhaps use SN74LVC06A powered from +3.3V.

Something along these lines? Agains, sorry for the sketch. I'm on the tablet!

[dc42]

Yes, that's what I had in mind.

Along with some other I/O conns ...
