From the project

An universal sophisticated USB-serial converter

SEE PROJECTHOMEPAGE UNDER https://www.seegel-systeme.de/2025/07/10/allserial

Over the course of time I had to work with many different devices which had to be connected via a kind of serial interface. There are lots of different cheap USB-serial adapters available, but no adapter was including all features I needed in a single device. Every USB-serial adapter has in common the USB Controller. So I came up with the idea having a masterboard providing all the common features like USB interface, isolation and diagnostic elements. The most used interfaces (RS232, RS485, TTL UART, TTY current…
