USB‑to‑TTL Serial Adapter – Fast, Reliable MCU Interface

This compact USB‑to‑TTL adapter transforms a standard USB‑A 2.0 connector into a 3.3 V or 5 V TTL serial interface, making it ideal for programming, debugging, and data exchange with microcontrollers, FPGAs, and development boards. With on‑board voltage‑level conversion, each data line is protected against voltage spikes, ensuring safe operation across a wide range of target devices.

Designed for high‑throughput serial communication, the cable supports full‑speed USB (up to 12 Mbps) and offers robust shielding and low‑latency data transfer. A 2 m length gives flexibility without compromising signal quality, and the compact ATxmega test fixture provides a stable mount for prototype boards.

• USB Standard: USB‑A 2.0, full‑speed 12 Mbps
• Logic Levels: 3.3 V or 5 V (hardware switchable)
• Current Rating: 500 mA source for power‑refeed or active debugging use
• Common Use Case: Arduino, STM32, ESP32 and other MCU serial programming or real‑time debugging
