This board allow to plug PS/2 devices (keyboards or mice) to a computer using a standard USB connector.
- Uses a low cost STM32F103 "bluepill"
- Two independent PS/2 ports
- Each port can be connected to a mouse, a keyboard or left unconnected. The connected devices are automatically presented to the host computer
- Automatic recognition of the type of the PS/2 device : you can connect any keyboard or mouse on each of the PS/2 connector of the board
- No specific driver required on host computer
- Hardware and Firmware source code provided
- 2 LEDs per port for PS/2 device type identification and traffic information
Directories:
- din2usb_adapter contains the KICAD files of the board.
- stm103_ps2_to_usb contains the firmware.

Questions
How big is the Din2usb adapter PCB?
It measures 82.6 × 49.5 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Din2usb adapter use?
20 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Din2usb adapter KiCad files?
From the ef15c/PS2_to_USB_converter repository on GitHub, at the commit this page was made from: the board is din2usb_adapter/din2usb_adapter.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Din2usb adapter design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
