Thanks for confirming!
I see that your web site listed multiple firmware versions since 2019.
If Amazon USA still have very old hardware, like those made in late 2018 and shipped to Amazon warehouse in late 2018, would those Tone1 from late 2018 comes with firmware older than v1.04?
Thanks!
I don’t think there still have any stocks with 2018 batches, and existing stock on any platforms including our distributors should be produced in 2020.
Just a reminder that the 2018 is design code rather than the date code of the producing date of PCB board.
Good day!
