I want to build a nice room temperature control using
[ul]USB Ser SP (Sock Prog) https://www.ghielectronics.com/catalog/product/437
RS485 Module (Sock U) https://www.ghielectronics.com/catalog/product/479
N18 DIsplay (Sock S) https://www.ghielectronics.com/catalog/product/425
Temp&Humidity (Sock X) https://www.ghielectronics.com/catalog/product/344[/ul]
But I need 3 additional push buttons, which I would have connected to any available X or Y socket.
But all sockets are used already.
Can anyone tell me if these modules would leave 3 GPIO’s free, so I could squeeze my buttons in between by breakout boards?
At least my Prototype would be built from std Gadgeteer modules. Hope they fit in a standard German socket ‘box’. (Except USB Module, This I would replace with power only when mounted to wall.)
For the outer part I would use my old Temperature controller housings from Bush Jäger (The display + 3 buttons should just fit in
The valves would be controlled by a standard RS485 capable Dig Out Module with built in relais for 230V (like ICP CON I-70 61 http://www.icpdas.com/products/Remote_IO/i-7000/i-7061d.htm)
