SKU CH-TYCY-9C0MB

USB-to-serial converter with CP2102 chip, 3.3 V TTL levels, RS-232 interface and 2.54 mm 6-pin header for debug terminals

  • CP2102 chip provides reliable USB to serial conversion
  • RS232 interface enables legacy device connectivity
  • 3V TTL logic ensures microcontroller compatibility
  • 6-pin 2.54mm pitch fits standard debug headers

CP2102 UART 3.3V Debug Cable

This USB serial adapter uses the CP2102 chip to provide an RS232 3.3V TTL UART converter. The six-pin connector has a 2.54 mm pitch for standard header compatibility. It serves developers and engineers who need a reliable debug terminal link.

3.3 V logic level decides compatibility

The interface operates at 3.3 V logic, so it suits targets that accept that voltage directly. Boards requiring 5 V TTL or true RS-232 levels will not work with this cable without additional level-shifting circuitry.

Questions about this item

What does the CP2102 chipset actually do inside a PC?

It converts a USB port into a 3.3 V TTL serial link so the host can talk to microcontrollers, routers or other UART devices.

How does the RS-232 label relate to the 3.3 V TTL output on the 6-pin header?

The adapter presents logic-level TTL signals at 3.3 V on the 2.54 mm pitch header; it does not generate RS-232 voltage levels.
