GreatFET One

Introduction

If you’ve ever asked yourself the question: How do I talk to this piece of hardware : The GreatFET one is the answer.

Rounding up multiple individual tools in a powerful, complete, easy-to-use package, the GreatFET one is a hardware hacker’s best friend.

Out-of-the-box use cases include:

• Logic Analyser
• Hardware debugger
• USB Sniffer
• Pattern Generator
• Bit-Banger
• Data logger
• Reverse engineering

The GreatFET One has ample hardware features:

• Native Serial Protocol support: SPI, I2C, UART, JTAG
• Programmable Digital I/O
• Programmable Analog I/O (ADC/DAC)
• 100 GPIO Pins
• Dual USB Ports (Fullspeed for target devices, Highspeed for host device)
• On-board 3.3V regulator
• 2MB Onboard flash
• 4x Programmable LEDs
• 2x Programmable Buttons
• Expansion shields or “neighbours”

Robust Software

The GreatFET’s killer feature is its software: a comprehensive Python 3 API that covers all all of the GreatFET’s hardware features.

The use of Python APIs allows hackers to connect, interact and develop on the same device: No need to debug your debugger, no need to string together multiple tools.

As with all devices from Great Scott Gadgets, the GreatFET One is fully open-source, with comprehensive documentation online.

The GreatFET One pairs well with the Daffodil, a shield designed to make breadboarding and semi-permanent prototyping easy.
