A compact USB-to-TTL serial interface for makers, simplifying programming and debugging of microcontrollers. DORHEA FT232RL USB to TTL Serial Adapter brings clear visual feedback and selectable logic levels for confident prototyping. Is it the dependable converter that keeps uploads and serial monitoring simple in a workshop or classroom?
⚡ At a Glance
- • Interface Compatibility: Type-C to UART bridge, selectable 3.3V or 5V logic, RX/TX LEDs
- • Best for: Hobbyists and electronics students needing reliable serial programming
- • Not ideal for: Users requiring native Windows 8 driver support
FT232R chipset converts USB-C to a UART serial port while exposing RXD/TXD and DTR pins. Selectable 3.3V or 5V logic and a self-restoring 500mA fuse add flexible, protected operation.
Stable Serial Communication - With FT232R Type-C USB-UART Bridge
FT232R chipset implements USB-to-UART translation and creates a virtual COM port on the host, while RXD and TXD pins carry TTL-level serial data. Type-C connection supplies data and power over a single cable.
Consistent serial transfers for programming and debugging, with visible RX/TX activity to confirm communication.
Safe Power Handling - Thanks to Selectable Voltage and 500mA Fuse
Type-C interface supports either 5V or 3.3V logic levels, or direct target voltage applied to VCC and GND pins. Overcurrent protection uses a self-restoring 500mA fuse to limit faults.
Reduced risk to host ports and target boards during experiments, with an option to match common MCU logic levels.
Smoother Uploads and Debugging - With DTR Auto-Reset and LEDs
A DTR pin is provided to trigger automatic resets on many microcontrollers during serial bootloading, and RX/TX indicator LEDs show live traffic. That combination mirrors the workflow used when uploading sketches to Arduino-style boards.
Faster, repeatable firmware uploads and clearer troubleshooting when uploading or monitoring serial output.

❓ Frequently Asked Questions
Q: Can I use the adapter with 3.3V microcontrollers?
A: Yes. The interface supports an optional 3.3V logic level, or a target voltage can be supplied directly on the VCC and GND pins.
Q: Will uploads reset the microcontroller automatically?
A: Yes. A DTR pin is included to allow automatic reset during serial downloads on boards that use DTR for bootloading.
Q: Which operating systems are supported?
A: FT232RL supports a range of older Windows versions including Win95 through Win7 and Vista in 32-bit and 64-bit flavours; Win8 is not supported.
