So what is wrong with ATR-poly?.
What's right? It's Polyethylene. It's almost impossible to glue an FR-4 PCB to it. And it's not what you call stable. For those of you that did not know I moved last Labor Day. About 4 months ago when I when in I was stunned to find out they have a Poly-Printer and give you the filament to boot! Today I ran off my first prototype it's 7' x 7' x 1" with .5" square supports in the corner to hold the cove on. The final size will b 7' x 8' x 3"
My baseboard holds the Arduino Meg R3, When I buy my Arduinos I buy them without the headers installed. I take those solder tail headers and solder them to my baseboard. And then I have headers with long that are soldered on to the Mega. All of the Arduino pins are then brought out to wire-wrap posts. I also have room on the baseboard to mount my RS-485 adapter and 4-bit dip switch for slave addressing. And room for two relays for lighting etc. Please forgive me but the first two that I will build is for one controller and one slave.
They are slightly different
| TYPE | DIN-5F | USB & Power | Ethernet | Dual RJ45 |
|---|---|---|---|---|
| rear | front | front | rear | |
| Controller | X | X | X | |
| Slave | X | X | XX |
