BDD FT232RL USB-C to TTL Serial Converter Module FTDI Arduino Adapter

The BDD FT232RL USB-C to Serial Board is a compact and versatile USB-to-TTL serial converter module designed to provide seamless communication between computers and microcontroller-based systems. Built around the widely used FT232RL USB-to-UART interface chipset, this module enables easy programming, debugging, and serial communication for Arduino boards, embedded systems, and DIY electronics projects.

Featuring a modern USB Type-C interface, this upgraded version ensures improved connector durability, reversible plug orientation, and broader compatibility with contemporary laptops, PCs, and development environments. It provides a simple and reliable way to add USB connectivity to microcontroller systems for firmware uploading, bootloading, and serial data exchange.

The module supports both 3.3V and 5V logic levels, making it suitable for a wide range of microcontrollers including Arduino, ESP8266, ESP32, STM32, AVR, PIC, and other TTL-based systems. It functions as a bridge between USB and UART communication, converting digital signals for easy integration with development boards and breadboard circuits.

An onboard DTR pin enables automatic reset functionality for Arduino boards during programming, streamlining firmware uploads and eliminating the need for manual reset operations. This improves development efficiency and simplifies iterative coding workflows.

The module also includes RX and TX LED indicators, providing real-time visual feedback for data transmission and reception. A built-in 500mA self-resetting fuse provides over-current protection, ensuring safe operation and protecting both the module and connected devices from electrical faults.

Please note that this version uses a non-original FT232RL chipset, does not include EEPROM functionality, and does not support signal inversion. It is intended for standard USB-to-TTL serial communication and general development use.
