It looks a nice toy for low power devices, indeed. And its onboard RS232
, by the lack of Rx/Tx , is the oddest one I've seen in 30+ years since
I deal with serial interfaces ( burnt the first one in '87 on my
Commodore 64 ). OTOH it seems that , after connecting the "?Extension
Modul" the serial starts to behave like a regular one ( that is, it has
all the usual pins and signals ). I guess that a driver for it could be
written by a passionate who has access to a board, given that

seems to provide the communication protocol. OTOH, RS232 in 2022 seems a
bit .. ancient, the world transitioned to USB a long time ago. But
looking at the electronic schemes they include, I kind of understand the
reasoning behind their choice... although a USB interface is not so hard
to implement nowadays.
