Quick Overview

USB to 3.3V/5V TTL Auto Sensing Adapter

Availability: In stock



Manufacturer: GearMo


This USB to 3.3V/5V TTL Auto Sensing Adapter allows you to connect your computer through USB port and use it as a regular serial UART (TTL level) communication port. All USB protocol is handled within the adapters connection to the computer. There is no other device or programming required as the adapter is perfect for embedded systems that require a serial connection to a computer.

The board attaches directly to the USB bus via a standard type A receptacle connector. It is recognized on any Windows computer as a standard serial COM port. Any applications that talk to this COM port are automatically converted to USB and back to UART to your target board.
