TTL-232R-3V3 USB to TTL Serial Cable 3.3V 4-Pin Header UART Converter Adapter FT232RL USB 2.0 Full Speed Interface TXD RXD VCC GND 300 Baud to 3 Mbaud Compatible with Windows/Linux

Product Description:

TTL-232R-3V3 USB to TTL UART converter cable for connecting TTL-level serial devices, microcontroller UART interfaces, or I/O pins to a USB port. The cable provides 3.3V TTL serial communication through a built-in USB-to-asynchronous serial interface.

Core Selling Points:

Provides a direct connection between USB host systems and TTL-level serial devices. The 4-way header outputs TXD, RXD, VCC, and GND with color-coded wires: white, green, red, and black. The internal interface circuitry handles USB signals and protocols, supports low USB bandwidth consumption, and includes a user-writable EEPROM area. Suitable for programming boards compatible with Raspberry Pi, Odroid C4, and BeagleBone Black.

Before Purchase:

Confirm that your equipment uses 3.3V TTL-level UART signals and matches the TXD, RXD, VCC, and GND connection layout. The cable is compatible with Windows and Linux systems and can be used with boards compatible with Raspberry Pi. This is a TTL serial interface cable, not a direct connection for interfaces using different voltage levels or signal standards.
