SKU: CAB-021 Mfg Part Number: Categories: , , , Tags: , ,


When working with microcontrollers, single board computers, serial based sensors, or console ports TTL Serial is a must. This simple USB to TTL Serial cable converts standard USB to TTL Serial. A cable inside the USB connector does all of the conversion work, and is broken out to 4 individual connectors.

The power pin is broken out directly from the USB port and supplies 5VDC at 500mA while the RX/TX pins are 3.3VDC logic; making this cable compatible with both 3.3 and 5V logic level chipsets.

The four wires are as follows: Red power, Black ground, White RX into the USB port, Green TX out of the USB port.



  • Cable Length: 92cm / 36″
  • 3.3V & 5V Logic Compatible
