[ CABLE / ADAPTER RECORD // FTDI FT232R USB-TO-UART TTL ]
USB-to-TTL UART 3.3 V FT232R Cable
Type-A USB to UART leads: TXD/RXD/GND and sometimes 3.3 V VCC/CTS/RTS; logic-level, not RS-232.
CLASSIFICATION: Serial and converter cables. Identify protocol, direction, pinout and exact cable revision before connection.
Interface and capability
| Standard / protocol | FTDI FT232R USB-to-UART TTL. Connector appearance alone does not establish compatibility. |
|---|---|
| Endpoint / pinout | Type-A USB to UART leads: TXD/RXD/GND and sometimes 3.3 V VCC/CTS/RTS; logic-level, not RS-232. |
| Capability / limits | USB Full Speed host link; UART baud is configured by driver/target. Cable lead length is product-specific. |
| Certification / length | Standards define interface requirements, not every assembly’s performance. Certification, mode, current/power rating, direction and maximum length belong to the exact product/revision and complete channel; verify its manufacturer specification. Do not infer certification from connector shape or marketing terminology. |
Compatibility & handling
- Set logic voltage and VCC correctly; cross TX/RX and share ground. Never connect directly to RS-232 DE-9.
- Inspect connector keying, latch, contact condition, shielding, jacket and model/revision marking. Stop if contacts are bent, loose, scorched, corroded or mismatched.
- Route without tension or sharp bends; follow product bend-radius, strain-relief, current and environmental limits. Test at the intended protocol and mode—physical fit is not a compatibility test.
