Ruth's sister CP2102 3.3V TTL UART serial converter internal power cable

SKU CH-P3G2-2KTVQ

Converts USB to 3.3 V TTL serial using a CP2102 chip with TXD, RXD, GND and dual 3.3 V or 5 V output pins

  • Silabs CP2102 chip enables reliable UART serial conversion
  • 3V TTL logic levels ensure direct microcontroller compatibility
  • TXD, RXD and GND pins provide essential serial connections
  • Dual 3.3V and 5V output rails power target devices directly

CP2102 3.3 V TTL UART converter

This internal power cable carries a Silabs CP2102 chip that converts USB signals to 3.3 V TTL UART levels. It exposes TXD, RXD and GND pins plus selectable 3.3 V and 5 V output rails. The adapter suits engineers, hobbyists and repair technicians who need a direct serial link to microcontrollers, routers or embedded boards.

Replaces bare USB-to-serial dongles

The board integrates the level shifter and power pins into a single internal cable, removing the need for separate adapters and loose jumper wires. The jump is worth it when a permanent, inside-the-case connection is cleaner than an external dongle or when the target device requires both 3.3 V and 5 V supply options from one header.
