Blahaj Studio USB TTL Adapter with FTDI FT232RNL [1.8 V / 3.3 V / 5 V] – USB-C to UART Serial Converter with 350 mA output, ESD protection, hardware flow control (for Windows, Linux, macOS & Android)

The Blahaj Studio USB-TTL adapter is designed for development, debugging, and serial communication in electronics and embedded projects. Unlike basic USB-to-TTL adapters, it supports logic and supply voltages of 1.8 V, 3.3 V, and 5 V, making it suitable for both traditional and modern low-voltage hardware.

At its core is a guaranteed genuine FTDI FT232RNL USB-UART chip. It supports data rates of up to 3 MBaud, hardware flow control, and a unique USB serial number. This allows the operating system to reliably recognize and assign the same adapter.

Advantages:

Flexibly adjustable: 1.8 V / 3.3 V / 5 V
For development, debugging & UART communication
Hardware flow control
Power, TX & RX status LEDs
ESD protection & resettable fuse
6-pin & 12-pin connectors
Windows, Linux, macOS & Android
