FT232RL USB-C to TTL Serial Converter Adapter Module

This FT232RL USB-C to TTL serial adapter module provides a convenient way to connect microcontrollers and breadboard projects to a computer. Supporting both 3.3V and 5V logic levels, it is well suited for makers, students, and hobbyists uploading code or debugging serial communication. A USB Type-C interface ensures modern cable compatibility for desktop and workshop setups.

Microcontroller programming

The module includes a DTR pin to facilitate the auto-reset required when uploading sketches or bootloading breadboard Arduino setups. It provides an accessible solution for serial communication and flashing firmware.

Protection and status indicators

USB power is protected by a 500mA self-restoring fuse to safeguard against over-current faults. Integrated RXD and TXD transceiver LED indicators give real-time visual feedback during data transmission.

Pinout and dimensions

Standard 2.54mm pitch pins break out DTR, RXD, TX, VCC, CTS, and GND lines for direct breadboard and jumper wire connections. The compact red PCB measures approximately 36mm in length by 17.5mm in width.

Chipset characteristics

This board is equipped with a non-original FT232RL chipset that does not include internal EEPROM and does not support signal inversion.
