## Description

A USB-to-UART (TTL) communication module based on the PL2303GS chip. Connect it to your PC via USB and communicate with microcontrollers, single-board computers, and other TTL-level serial devices. Three LED indicators (TXD, RXD, PWR) provide visual feedback during operation. The module supports flexible VCCIO configuration via an onboard jumper: output 5 V, 3.3 V, or leave open to accept power from the target board (1.8–5 V). Key Features PL2303GS Chip – Latest version for reliable USB-to-UART conversion TTL Level Output – Compatible with 1.8 V, 2.5 V, 3.3 V, and 5 V logic Selectable VCCIO – 5 V, 3.3 V, or external power via jumper 3 LED Indicators – TXD, RXD, and PWR status Windows Compatible – Supports Windows XP / 7 / 8 / 10 / 11 Wiring (Example: Type A with MCU) VCCIO → 3.3 V or 5 V (set via onboard jumper) GND → GND TXD → MCU RX RXD → MCU TX Warning: This module is compatible with TTL level only. Do NOT connect directly to RS-232 circuits — doing so may damage the module. Package Contents 1× PL2303 USB UART Board 1× 4-Pin Custom Connector Jumper Wire Resources Waveshare Wiki
