== Notes and version constraints ==
* The source references “FT32 Driver-Windows 64 bits”, likely a typo for “FTDI”; confirm the exact driver version before installation.
* COM port assignment may change; if recognition issues recur, pin the COM port manually.
* For power-supply problems with external devices (e.g., flickering TX/RX indicators), the source mentions an FTDI programming step; this requires FTDI programming software and human confirmation.
* The source contains several incomplete placeholders (“{{{name2}}}
* {{{userDefinedInfo}}}” etc.) that do not provide technical facts.
* Troubleshooting steps (driver swap, cable/port/PC replacement) are generic diagnostics and require hands-on verification on the device.
* To verify functionality, shorting TXD and RXD and sending data through a serial debugging tool is recommended; this requires a suitable tool and a physical connection.
* The source warns about low-quality knock-offs; chip authenticity should be verified before deployment.
