I've got two things that I have no use for that may be useful to others, and I'd be quite happy to drop them in the mail to anyone who might want them.
First item is a small module, an Espressif ESP-WROOM-02, which I believe came out of a Roomba vacuum that was given to me:

Second item is a Linx development board, marked "MS/HS master development system":

So far as I know, these are both working. Both have no visible signs of damage. Of course, I can't be sure about this, but hey, they're free!
If you want either one send me a PM. The only thing I won't do is mess with any customs stuff, so if that's the case for the country you live in, sorry.
