Pinguino Automaton
Hello Guys,

After some month of works, I'm please to show you the first version of my Pinguino Automaton.

Hardware description:
12 opt-insulated inputs, 10-30 V
8 Relay outputs
1 Serial port RS232C
1 USB Port (obviously !)
1 Display port for alphanumeric LCD in 4 bits mode, with R/W at ground
2 User buttons. Theses input could be used in analog mode to increase the button nuber.
1 Reset button
1 Power LED
1 User LED
1 12V Power jack
It's designed to use a PIC18F45K50 but could be used with a PIC18F4550 (external crystal and 2 inputs lost)

Some pictures, Schematic and PCB layout below:

I designed this with KICAD. PCB was done by

It's a double sided PCB with metalized holes and ground planes.
It cost approximately 10€ for PCB and 100€ for the equipped circuit.

I waiting for your comments and suggestions.

Congratulations on the Project! Smile
Do you already have an use for that circuit to use all those outputs? Big Grin

In my job, I'm testing automotive products like electronics Windows regulators or sun roof.
I use Siemens Logo automaton (8 inputs and 4 outputs) and often the application needs an extension module (4 inputs and 4 outputs) It's exactly the I/O number of the Pinguino Automaton.
If needed, it's possible to use some outputs with one or two full bridge to drive brushed motor or stepper motor.
