Whether you need an interface to an external chip, a logic analyzer, a debugger, or just a whole lot of pins to bit-bang, the versatile GreatFET One is the tool for you. Hi-Speed USB and a Python API allow GreatFET One to become your custom USB interface to the physical world.

GreatFET is designed to provide a significant step up in capabilities from GoodFET while making the design manufacturable at a lower cost than GoodFET. In addition to being designed for automated assembly, it can be hand-assembled with a soldering iron, though it is a more complicated assembly than GoodFET. An important similarity to GoodFET is that GreatFET has a USB bootloader in ROM, so it is possible to build a board by hand and install firmware onto it without the need of any external programming hardware.

  • Programmable digital I/O
  • Serial protocols including SPI, I2C, UART, and JTAG
  • Logic analysis
  • Analogue I/O (ADC/DAC)
  • Data acquisition
  • Debugging
  • Versatile USB functions including Facedancer
  • High-throughput hardware-assisted streaming serial engine
  • Four fabulous LEDs!

Technical Specs: 

  • LPC4330 microcontroller (U1)
  • Hi-Speed USB port (USB0) for connection to a host computer
