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 loop & LIN) are build up on slave modules which can be plugged into the mainboard. If a custom interface is needed, there is an KiCad library available making it easy to create one by yourself.

Features

• Open source
• Isolated
• Reset button for reenumerating device on the USB
• Status LEDs (RX, TX, Power, TXEN)
• modular, just exchange daughterboard for different interfaces
• RS232 completley connected (RXD, TXD, RTS, CTS, DTR, DSR, RI, DCD)
• RS485, RS422 with Handshake
• TTY current loop 4/3/2 wire active/passive
• LIN
• TTL 1.8/2.5/3.3/5 V
• KiCad library for easily creating custom modules

Modules (tested & working)

• Mainboard FT232
• RS 422/485
• RS 232
• TTL
• TTY current loop
• LIN
• 1wire (with DS2480B)
• Programmer for ESP8266 (auto reset&boot)

Modules (under development)

• Mainboard with ESP32-S3 for accessing slave modules via USB, WiFi & Bluetooth
• mBus master
• Digi XBee radiomodem
• eBus

Software

• hterm (windows)
• putty (windows/unix)
