Thank you Gerry for putting this topic up for me.
As a listener and creator of this daughter board. I have a rough ideal about features and layout to startup with.
-2 LPT in one daughter board
-Second Charge Pump. ( A request from Gerry. UCCNC has second CP signal)
-13 npn isolated inputs 24V. (This is for NPN sensor ans normal switches)
-13 npn/pnp isolated inputs 5v/24V. (general inputs for all type of sensors, switches and devices to interface to UC300eth)
-8 npn sink output (same as its mother board)
I took out some unnecessary fancy things to make it in reasonable price.
However, please raise your issue or your need about this board.
