I wish to add serial in/out via USB to my custom arduino.
So I currently have 3 options as far as I can tell.
1: Use a serial to mini-usb breakout adapter I have. Of course this is the most direct solution. But the circuit board doesn't have any sort of mounting holes, and I really don't want to use glue and tie strips to mount a board I am going to use force to use the usb port of a dozen times a day.
It's also rather large and doesn't fit on my device in any neat and natural way.
2: Use a ATTINY ready on a board from digispark I also have.
Can I use this board to program my bot, or perhaps bypass the ATTINY and use the USB port and serial handling circuitry for my custom arduino directly?
This board would fit perfectly if this is possible.
3: Try to find another module and wait another month or 2 for shipping.
If you think this is the best option, do you have any suggestion for small serial modules with attachment points? I have been searching for replacements, but I haven't found the best options so far.
My device is built on a solderable breadboard, so I can also build my serial circuitry myself if you believe this is doable.
