Internal WiFi modem for the STBook.
Posted: 15 Jan 2026 01:15
Hello!
The STBook was designed with space for an internal modem (to be installed under the Vector pad). None (to my knowledge) was made and/or released at the time, so I saw a great opportunity to make some hardware for this beautiful machine. It is based on an ESP32-C3 supermini dev board. You can get the instructions, the gerber files, the software, the firmware here: https://github.com/AndresPlazaR2/STBook_Modem
You can SSH to servers or telnet to BBS, of course:
(here connected to @Darklord 's BBS).
I hope somebody found this useful. :-)
