{"title":"USB to TTL 4-pin Wire","handle":"usb-to-ttl-4-pin-wire","url":"/products/usb-to-ttl-4-pin-wire","description":"A USB to TTL serial adapter cable with an embedded PL2303 converter chip. This 1-metre cable provides a simple way to add serial communication to your projects, connecting a standard USB-A port to 3.3V TTL-level UART signals via a 4-pin 2.54mm header.\n\nIdeal for accessing serial consoles on single-board computers like Raspberry Pi, debugging microcontrollers, or communicating with any device that uses TTL-level serial.\n\nKey Features\n\n\nPL2303 Converter Chip – Reliable USB to UART bridge with wide OS support\n\n3.3V TTL Logic – TX and RX lines operate at 3.3V, safe for modern microcontrollers\n\n5V Power Output – VCC pin provides 5V from USB for powering target devices\n\n2.54mm Pin Header – Standard pitch for easy breadboard and header connections\n\n1m Cable Length – Generous length for comfortable bench use\n\n\nPinout\n\n\nRed – VCC (5V)\n\nBlack – GND\n\nGreen – TXD (3.3V TTL, connects to target RXD)\n\nWhite – RXD (3.3V TTL, connects to target TXD)\n\n\nCompatibility\n\nWindows XP, 7, 8, 8.1, 10 and later\nmacOS and Linux (driver support may vary)\n\n\nIdeal For\n\nRaspberry Pi and single-board computer serial consoles\nMicrocontroller UART debugging and programming\nSerial communication with GPS modules, sensors, and other TTL devices\nEmbedded system development and diagnostics\n\n\nPackage Contents\n\n1× USB to TTL 4-pin serial cable (1m)\n\n\n\nNote: The TX and RX lines are 3.3V TTL level. Do not connect directly to RS-232 level signals, which may damage the converter.\n","vendor":"Waveshare","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":3943,"title":"Default Title","sku":"WS-7965","price":3.29,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":10,"option1":"Default Title"}]}
