I need a circuit designed.

I need 6 relay outputs, 6 opto-isolated inputs, 2 Analog Inputs (1 suitable for RTD), 2 Analog Outs, A 4 pin connector for LCD display over i2C.

In fact everything above should be for I2C control.

Then I need some headers to a processor - pick some arduino this may change but again so far it should all be I2C so it shouldn't matter.

I want a power circuit that can take in just about any power source. Let's see what you can come up with here.

The processor needs to be optional - I am thinking DIp switches/jumpers to connect the I2C. All cards need to be on a bus so they can be daisy chained. So I can plug in 1 processor, connect another card and that processor controls it all. The card needs to be addressable for all the IO on it.

Also ADD some leds - 4 to 8 of them. small for diagnostics.

Do you want only the schematic and BOM, or you want PCB and Gerber files? The bid may change depending on your answer.

I can do this design, not sure what to write here. I have few questions, like what do you mean by the bus? If I understand correctly, you want to control your relays via the I2C? And other boards via the same I2C bus? Más
