Nano Connectivity
Tom, Blair, All,
As you have already guessed, I'm leaning towards having a 'plug in' Nano arrangement of the proposed PCB. This is fine for a Serial output. If we wanted the network connection, which I think is a very good idea, then maybe using an ENC28J60 Ethernet Shield that the Nano plugs into is an option? Everything is all on the board still. What do you think? Is this an easy option?
I'm not sure if there is any/much interest in a WiFi version, but I was thinking it might be nice to make provision for it in the form of a Node MCU such as an ESP-01 (ESP8266 based). They are certainly very cheap, but their voltage requirements would need additional circuitry on the PCB. I'm not sure how big they are, but for ?2.00, I might just get one to see! Being a separate unit, they could of course be used with the Uno and Mega if people didn't want to buy the WiFi enabled version of those.
Just throwing a few thoughts in.
Steve
