{"title":"Adafruit Floppy FeatherWing with 34-Pin IDC Connector","handle":"adafruit-floppy-featherwing-with-34-pin-idc-connector","url":"/products/adafruit-floppy-featherwing-with-34-pin-idc-connector","description":"The Adafruit Floppy FeatherWing lets you read and write 3.5-inch or 5.25-inch floppy disks using a Feather microcontroller. It connects to standard 34-pin IDC floppy drives and includes built-in level shifting between 3.3 V Feather logic and the 5 V signals that floppy drives require.\n\nFloppy drives stream raw bit transitions at high speed, so a fast microcontroller with large SRAM and DMA capability is needed. This FeatherWing is currently supported with the Feather M4 and Feather RP2040 only — ESP32, ATmega, nRF52, and other platforms have not been ported.\n\nKey Features\n\n\n34-Pin IDC Connector – Pre-attached 2×17 header for standard floppy drive cables\n\n5 V Level Shifting – On-board boost converter provides 5 V logic output and shifts incoming signals to 3.3 V\n\nWrite Disable Switch – Physically prevents accidental writes, ideal for archiving use cases\n\n3.5-inch and 5.25-inch Drive Support – Works with both form factors\n\n\nSupported Use Cases\n\n\nData Archiving – Read raw bit patterns from floppy disks for preservation; compatible with Greaseweazle and FluxEngine command-line tools running on your computer\n\nFAT Disk Read/Write – Read and write FAT-formatted floppy disks from Arduino or CircuitPython, or via USB connection to a computer\n\nFloppy Music – Drive stepper motors for musical sequencing projects\n\n\n\nImportant: Floppy drives require external 5 V power at up to 2 A — they cannot be powered from USB alone. 5.25-inch drives also need a 12 V supply.\n\n\n\nNote: Only compatible with Feather M4 and Feather RP2040 boards. You will also need a 34-pin IDC cable, a floppy drive, external power supply, and floppy disks — many of these items are vintage and may require sourcing.\n\n\nIdeal For\n\nFloppy disk data archiving and preservation\nRetro computing projects\nInterfacing modern microcontrollers with legacy storage\n\n\nPackage Contents\n\n1× Floppy FeatherWing with 34-pin IDC connector and level shifting circuitry\nPin headers for Feather connection (unsoldered — assembly required)\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":1786,"title":"Default Title","sku":"AF-5679","price":10.58,"on_sale":false,"in_stock":true,"available_quantity":100,"option1":"Default Title"}]}
