As a resident of the "imperial" U.S. I had to do a CM to Inches conversion on those board dimensions. Thats huge....
Yes, I forgot you are really one of our colonies
There are 3 of those boards going in along with some 'smaller' 15 x 10 CM boards (6" x 4") as sub boards and also just connector boards with, say, a 40 pin in and many different output types.
You can see the centralised approach used here
https://sismo-soluciones.com/index.php? ... r=category and they run a downmarket (
) version of what I am putting together. No seriously, there stuff is good, but there are better hardware options now that can be built for pennies and there are things I require that they simply cannot do.
Everything will be plug in modules - even the processors like the pico will plug to a 'main board'
I like their gear but it is too restrictive, too expensive and it doesn't do all I want it to do.
For example, I reckon a 128 pin input board to my design will cost less around 20 dollars in parts and be bullet proof. Similar price for the output boards with 15mA drivers and also boards with 150mA and 500 mA per pin (outputs), as well as addressable RGB leds. Similar again - around 20 to 30 dollars target price in parts - for motor drive units, high current DC, stepper and servo. No pcbs so anyone can play along at home..
Fixed soldered connections and screw connections are a total non starter for me, it has to be plug in. The investment in tools is easily recovered - luckily, I have all the tools but they aren't expensive really. The main cost is in the connectors , plugs, sockets, headers and wiring, not in electronics, and imho you need those connections anyway in something like a home cockpit with hardware, as you have demonstrated.
It's all good fun.
