Question: has anyone experimented with the serial port on the Arduino Opta? On the Uno et al there are pins broken out as Rx and Tx, but I’m not sure the Opta has this functionality. One could probably do some sort of breakout with the USB-C port, but perhaps there is an easier way. I think it may have more than one serial port, available, but not certain.
Looking for the connector that Arduino uses to mount up their expansion modules to the Opta PLCs. Any ideas? These search parameters on Digikey should be similar: https://www.digikey.com/en/products/filter/edgeboard-connectors/303?s=N4IgjCBcoEwJxVAYygMwIYBsDOBTANCAPZQDaIAzACwBsVcA7CALqEAOALlCAMocBOASwB2AcxABfQjQTQQKSBhwFiZSjDBgArAAYW7LpF4CR4qSAAcFxPLRY8hEpHI0KcCzX0hO3PkLGShBayyHbKjmqMMJ6s3obG-maEWhSecgpKDqrOIAw0NFpePkZ%2BppLmMGoARkTo-AAmAAQcRI01dU1IRMLCuEgt-CwSQA however, I need the sides to be open and preferably have it keyed so it doesn’t reverse. One side could be solder-on contacts conceivably, but would be good to know where I can find something exactly the same specs-wise.
Alright, it appears this is it, or at least the same specs: https://www.newark.com/avx-interconnect/009159010061916/card-edge-conn-dual-side-10pos/dp/85W8864?cfm=true
