UC300ETH-5LPT with 3rd part BOB

[Corwax]

Hi there!

Couple of years ago I've purchased UCCNC bundle (software, UC300ETH-5LPT and UCBB).
That was "long story" project. Now I'm going to implement it in another CNC. And I've faced with output pins shortage. Actually - I need another 4 output pins, litteraly.

UC300ETH-5LPT has 5 "LPT Ports" and only 2 of them (Port1 and Port2) occupied by UCBB (CN2 and CN2) accordingly.
The question is: can I connect another .... "breakout board" from aliexpress to have a couple of IO pins in addition to UCBB.
To be more precise - I'm talking about this two types of chinese BOB

Yes, you can.

Thanks ger21, just one more thing... Which port on UC300 I must use? Standart or bidirectional?

Regards...
