Product Features: 1. FT232RL Chip: The USB to TTL converter uses the original FT232RL chip, providing better stability and compatibility for industrial-grade high-performance communication between computers and TTL devices. 2. High Performance: The USB to TTL converter adapter incorporates a self-resetting fuse, ESD and IO protection diode circuits, and is compact and exquisite. 3. System Compatibility: The industrial-grade USB to TTL converter supports Win7/8/8.1/10/11, Linux, Android, WinCE, and other systems; it supports hardware streaming. 4. Indicator Lights: The USB to TTL module has three data indicator lights for easy viewing of the working status, facilitating programming and debugging, and can provide 5V or 3.3V voltage to external devices (set via a switch). 5. Note: This universal USB to TTL converter does not include a USB cable. This module is USB to TTL level; do not connect directly to RS232 level connections to avoid damaging the module.
