With two USB ports — one host and one peripheral — it can act as a man-in-the-middle for USB interfacing, making it an essential tool for hardware hacking, reverse engineering, and custom USB peripheral development.\n\nThe board features 100 expansion pins and supports add-on boards called \"neighbours\" that extend its functionality. A Python API and Hi-Speed USB let you quickly turn the GreatFET One into a custom USB interface to the physical world.\n\nKey Features\n\n\nNXP LPC4330 Processor – Cortex-M4 at 204 MHz\n\nDual USB Ports – One host, one peripheral for man-in-the-middle USB work\n\n100 Expansion Pins – Extensive I/O for custom interfacing\n\nPython API – Script-driven control over Hi-Speed USB\n\nExpandable – Add \"neighbour\" boards for specialised functions\n\nOpen Source – Fully open hardware and software design\n\nUSB Bootloader in ROM – No external programmer needed for firmware installation\n\n\nCapabilities\n\nProgrammable digital I/O\nSerial protocols: SPI, I2C, UART, and JTAG\nLogic analysis\nAnalogue I/O (ADC/DAC)\nData acquisition\nHardware debugging\nUSB functions including FaceDancer\nHardware-assisted streaming serial engine\n\n\nIdeal For\n\nUSB reverse engineering and protocol analysis\nHardware security research\nCustom USB peripheral development\nEmbedded systems debugging and interfacing\n\n\nPackage Contents\n\n1× GreatFET One board\n1× Hi-Speed USB cable\n1× Wiggler (for separating neighbour boards)\n\n\n\nNote: Enclosures and neighbour boards are sold separately.\n\n\nResources\n\nGreat Scott Gadgets\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":5149,"title":"Default Title","sku":"AF-4234","price":239.76,"on_sale":false,"in_stock":true,"available_quantity":23,"option1":"Default Title"}]}
