Description

Compact USB‑A to TTL UART cable designed for firmware flashing, serial debug and direct console access to microcontrollers, dev‑boards and embedded devices. The cable integrates a reliable USB‑to‑serial converter (FTDI‑class or equivalent) inside the molded USB housing and delivers a virtual COM port on Windows, macOS and Linux. Available in common Dupont header configurations (3‑pin, 4‑pin and 6‑pin), and offered with selectable logic levels (3.3 V or 5 V variants) to match your target device.

The flat, flexible lead with reinforced strain reliefs is ideal for bench work and field use. Plug‑and‑play operation is supported where the host OS provides class‑compliant drivers; driver packages and quick‑start guides are supplied for systems that require manual installation. Suitable for Arduino, Raspberry Pi, ESP series, STM32/ARM boards, sensor modules and production programming.
