Isolated USB-UART

Isolated USB-UART is a galvanically isolated USB to UART converter. It is based on the FT232R and ADuM1201 IC's and offers speeds up to 3Mbaud1 with support for up to three data transfer pairs, RX/TX, RTS/CTS, and DSR/DTR, controllable by component mounting choices. Galvanic isolation of up to 1131V is achievable as per the IEC 60950-1 standard, making mains isolation easily achievable. A 2.7V to 5.5V output voltage range allows for communication with most devices. An optional mode supplies the load with 5V from the USB bus, though without any isolation.

This entire project is open source hardware and made available under the terms specified in each file. Commercial solutions are available upon request, see Desel.
