TMC4671-TOSV-REF is an open source reference design for ventilators / respirator systems. It is a BDLC servo driver for voltages from +12V to +36V and motor RMS phase currents up to 6A. It offers a wide range of connectivity with its SBC connector in Raspberry Pi style, the add-on board header for a standard or custom pressure sensor add-on board, and general purpose I/O. Communication is via standard TTL UART or RS485 (when using the standard add-on board TOSV-SENSOR-REF).
