We would like to Connect a numeric keypad using USB serial (or RS232/xxx) to the MangOH yellow device to receive user keystroke inputs as a string so that we can process the data on the edge.
Is this currently supported? and if so, what is the easiest and/or best way to achieve this?
The requirement is to capture a numeric input at the edge and send it to the cloud. Any pointers will be appreciated whether we should look at USB to UART or GPIO and also at a high level how this can be achieved.
Thanks in advance
