HiLetgo FT232RL USB to TTL Converter

This adapter provides a USB to serial UART interface using the FT232RL chipset. It operates at selectable 3.3V or 5.5V levels with a Mini USB connector. The board includes RXD/TXD activity indicators and a 500mA self-restoring fuse for protection. It suits developers debugging microcontrollers or flashing firmware on legacy hardware.

Works with Windows 95 through 7 32-bit

The module supports Win95, 98, ME, 2000, XP, Vista and Windows 7. It does not support Windows 8 or later operating systems. Buyers needing modern OS driver support should look at alternative solutions. This board targets maintenance of older equipment or specific legacy development environments.

FT232RL chipset not genuine FTDI silicon

The converter uses an FT232RL chipset noted as not a genuine FTDI component. Driver compatibility may vary depending on the host system and FTDI driver versions. Verify this constraint before integrating into designs requiring certified FTDI silicon. The pin header offers DTR, RXD, TX, VCC, CTS and GND connections.

Questions about this item

How much current can the onboard fuse handle before it trips?

The module includes a 500 mA self‑restoring fuse that protects the USB port from over‑current conditions.

Does the board generate noticeable heat during continuous data transfer?

The FT232RL chip runs at low power and the tiny PCB dissipates heat passively, so it stays cool in normal use.

Which operating systems are officially supported by the driver?

Drivers are provided for Windows 95, 98, 98 SE, ME, 2000, XP, Vista and Windows 7 (32‑bit and 64‑bit); Windows 8 is not supported.
