## Description

The GreatFET One from Great Scott Gadgets is a versatile, open-source hardware tool built around the NXP LPC4330 (Cortex-M4 at 204 MHz). 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. The 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. Key Features NXP LPC4330 Processor – Cortex-M4 at 204 MHz Dual USB Ports – One host, one peripheral for man-in-the-middle USB work 100 Expansion Pins – Extensive I/O for custom interfacing Python API – Script-driven control over Hi-Speed USB Expandable – Add "neighbour" boards for specialised functions Open Source – Fully open hardware and software design USB Bootloader in ROM – No external programmer needed for firmware installation Capabilities Programmable digital I/O Serial protocols: SPI, I2C, UART, and JTAG Logic analysis Analogue I/O (ADC/DAC) Data acquisition Hardware debugging USB functions including FaceDancer Hardware-assisted streaming serial engine Ideal For USB reverse engineering and protocol analysis Hardware security research Custom USB peripheral development Embedded systems debugging and interfacing Package Contents 1× GreatFET One board 1× Hi-Speed USB cable 1× Wiggler (for separating neighbour boards) Note: Enclosures and neighbour boards are sold separately.
