{"title":"SparkFun Beefy 3 - FTDI Basic Breakout","handle":"sparkfun-beefy-3-ftdi-basic-breakout","url":"/products/sparkfun-beefy-3-ftdi-basic-breakout","description":"The SparkFun Beefy 3 is an FTDI Basic Breakout board based on the FT231X USB-to-serial IC. Unlike standard FTDI breakouts, it features an AP2112K voltage regulator capable of supplying up to 600mA at 3.3V — enough to power a 3.3V project directly from the board's USB connection.\n\nThe 6-pin header matches the FTDI cable pinout and works with Arduino Pro, LilyPad, and other 3.3V Arduino-compatible boards. The DTR pin enables auto-reset when uploading sketches, so there is no need to press the reset button manually. TX and RX LEDs provide visual confirmation of serial traffic. Requires a Micro-B USB cable (not included).\n\nKey Features\n\n\nFT231X USB-to-Serial – Reliable FTDI-based serial communication\n\n600mA 3.3V Regulator – AP2112K powers 3.3V projects directly from USB\n\nDTR Auto-Reset – Automatic Arduino reset on sketch upload\n\nTX/RX LEDs – Visual serial traffic indicators\n\nFTDI Cable-Compatible Pinout – 6-pin header (BLK/GRN alignment markers)\n\n\nSpecifications\n\n\nIC – FTDI FT231X\n\nLogic Level – 3.3V\n\nRegulator – AP2112K, up to 600mA output\n\nConnector – Micro-B USB\n\nHeader – 6-pin (GND, CTS, VCC, TX, RX, DTR)\n\n\nPackage Contents\n\n1× SparkFun Beefy 3 FTDI Basic Breakout\n\n\nResources\n\nHookup Guide\nHow to Install FTDI Drivers\nSchematic (PDF)\nHardware Design Files (GitHub)\n","vendor":"SparkFun","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":11371,"title":"Default Title","sku":"SF-DEV-13746","price":37.2,"on_sale":false,"in_stock":true,"available_quantity":109,"option1":"Default Title"}]}
