NeoSWSerial won't work on the 12MHz Trinket. It doesn't even have a UART, so the Trinket Serial is actually a SoftwareSerial instance. :stuck_out_tongue:

This USI library might work. If not, the built-in SoftwareSerial might work... it's different code on the ATtiny MCUs from UNOs et al.

There's lots of ways for this to go wrong, so plan your pin usage very carefully.
