{"title":"SparkFun FTDI Basic Breakout - 3.3V","handle":"sparkfun-ftdi-basic-breakout-3-3v","url":"/products/sparkfun-ftdi-basic-breakout-3-3v","description":"The SparkFun FTDI Basic Breakout provides USB-to-serial conversion using the FTDI FT232RL IC, operating at 3.3V logic levels. Its 6-pin header matches the standard FTDI pinout, making it compatible with Arduino Pro, LilyPad, and other 3.3V boards that use the FTDI connector.\n\nThe board brings out the DTR pin rather than RTS, enabling auto-reset on compatible Arduino boards when uploading sketches — no need to press the reset button manually. TX and RX LEDs provide visual confirmation of serial traffic.\n\nKey Features\n\n\nFTDI FT232RL – Reliable USB-to-serial UART conversion\n\n3.3V Logic Level – Matches 3.3V Arduino boards and other targets\n\nDTR Pin – Enables auto-reset for sketch uploads on compatible boards\n\nTX/RX LEDs – Visual indication of serial communication\n\nSMD 6-Pin Header – Compact form factor with standard FTDI pinout\n\nMini-B USB Connector – Standard USB connection to host computer\n\n\nPin Alignment\nThe pins labelled BLK and GRN correspond to the black (GND) and green (DTR) wires on a standard FTDI cable. Use these markings to align the board with your target's 6-pin connector.\n\nIdeal For\n\nProgramming Arduino Pro, LilyPad, and other 3.3V FTDI-header boards\nGeneral-purpose USB-to-serial communication\nDebugging and serial monitoring\n\n\nResources\n\nSchematic (PDF)\nEagle Design Files\nUSB to Serial UART Boards Hookup Guide\nHow to Install FTDI Drivers\nGitHub Repository (Design Files)\n","vendor":"SparkFun","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":13564,"title":"Default Title","sku":"SF-DEV-09873","price":41.23,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":63,"option1":"Default Title"}]}
