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.\n\nThe 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).\n\nKey Features\n\n\nPL2303GS Chip – Latest version for reliable USB-to-UART conversion\n\nTTL Level Output – Compatible with 1.8 V, 2.5 V, 3.3 V, and 5 V logic\n\nSelectable VCCIO – 5 V, 3.3 V, or external power via jumper\n\n3 LED Indicators – TXD, RXD, and PWR status\n\nWindows Compatible – Supports Windows XP / 7 / 8 / 10 / 11\n\n\nWiring (Example: Type A with MCU)\n\n\nVCCIO → 3.3 V or 5 V (set via onboard jumper)\n\nGND → GND\n\nTXD → MCU RX\n\nRXD → MCU TX\n\n\n\nWarning: This module is compatible with TTL level only. Do NOT connect directly to RS-232 circuits — doing so may damage the module.\n\n\nPackage Contents\n\n1× PL2303 USB UART Board\n1× 4-Pin Custom Connector Jumper Wire\n\n\nResources\n\nWaveshare Wiki\n","vendor":"Waveshare","product_type":"","in_stock":true,"options":[],"variants":[{"id":1422,"title":"Default Title","sku":"WS-20645","price":5.15,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":102,"option1":"Default Title"}]}
