USB to TTL Converter

The AN-USB-TTL module is a cost-effective way to convert TTL signal a USB interface. When connected to a PC USB port the AN-USB-TTL module is automatically detected and is installed as a native COM port which is compatible with any existing serial communication application. When using USB hubs thus allowing a hassle free configuration of a multi serial system without any IRQ or DMA configuration. They have 600W protect between the USB port and TTL protects the PC from spikes or possible misconnections in the communication bus.
