USB Type C to DB-9 Adapter Cable - 1.5m Long 2 channel relay for raspberry pi This gives it stable handlingThis USB Type C cable adds a DB 9 (DE 9) serial port to your computer or laptop, compatible with MacOS X, Linux, and Windows. It provides approximately 6V serial (RS232) levels, making it ideal for connecting to older devices like GPS units, handhelds, and programmers with DB9 connectors. Unlike some cheaper RS232 cables that output 0 5V and may not work reliably with all devices, this adapter uses a true voltage doubler inverter for compatibility.
