USB Type C to DB-9 Adapter Cable - 1.5m Long

This 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.

These cables are tested and suitable for bit-bang serial programmers and adapters, though slower compared to hardware serial ports due to USB overhead.

Featuring an FTDI chip for better performance and reliability, drivers are solid and available for most operating systems. For RS-232 needs on computers with only Type A USB ports, check out the alternative cable here.
