FTDI USB to TTL Serial UART Converter Module

The FTDI USB to TTL Serial UART Converter Module is a development tool built around the FTDI FT232RQ USB to serial UART interface IC, supporting data transfer rates from 300 baud up to 3 Mbaud. It bridges USB and TTL-level serial interfaces, handling all USB signalling and protocols internally so that integration into projects is straightforward.

Overview

This compact printed circuit board (PCB) is intended for engineers and electronics hobbyists. It offers a USB 2.0 full-speed compatible connection and is entirely bus-powered, requiring no external power supply. The module is suitable for both direct integration into projects and use as a standalone programming and debugging interface.

Key Features

• Core IC: Integrates the FTDI FT232RQ for USB-to-serial conversion.
• High-speed data: Supports transfer rates from 300 baud to 3 Mbaud.
• Flexible handshaking: Provides hardware (RTS/CTS) and software (X-On/X-Off) flow control.
• Device identification: Supports FTDIChip-ID, where a unique serial number is programmed into each FT232R chip.
• Internal EEPROM: Includes a user-writeable area for custom configuration.
• Virtual COM port: The FT232RQ driver creates a virtual COM port (VCP) on the PC.

Applications

The header pins connect directly to a microcontroller's UART or I/O pins, enabling communication with microcontrollers, sensors, and other TTL-level devices. The FTDIChip-ID feature can be used to create password-protected or security-specific access for file transfers. Choose this module when you need a USB to TTL serial interface for connecting microcontrollers, sensors, and other TTL-level devices to a PC.
